Integrating Mathematics and Pedagogy (IMAP) Web-Based Beliefs Survey

Development of this Beliefs Survey was supported by a grant awarded by the Interagency Educational ResearchInitiative, National Science Foundation (NSF) (REC-9979902) to Randolph Philipp and Judith Sowder at San DiegoState University. The views expressed are those of the authors and do not necessarily reflect the views of NSF.

Introduction

This beliefs survey was designed to assess respondents’ beliefs about mathematics, beliefs about learning or

knowing mathematics, and beliefs about children’s learning and doing mathematics. Our target audience was

prospective and practicing elementary school teachers, although the survey has been used with others. This survey is

not designed to explicitly assess respondents’ beliefs about teaching mathematics, although inferences about these

beliefs can reasonably be made. We set out to construct a beliefs-assessment instrument that would go beyond the

typical approach of using Likert scales because we believed that beliefs are best assessed in context. Our instrument

is web-based, making possible use of video clips and minimal branching based on how one responds to particular

questions. Survey administrators can customize the beliefs survey, and responses are saved as Excel files to simplify

data collection and subsequent coding.

What Makes This Survey Special?

We took seriously the notion that an important means for assessing beliefs is to determine how respondents

interpret, react to, or profess to act within well-defined contexts. Unlike traditional Likert-scale instruments that provide

statements to which respondents agree to one degree or another, our survey requires respondents to use their own

words to interpret situations, predict results of particular actions, and make recommendations. We then make

inferences on the basis of their responses. Each belief is assessed by two or three rubrics associated with different

segments of the instrument. This instrument can be used to collect data from many people in a relatively brief period of

time, and the customizing feature will enable researchers to assess specific beliefs or select rubrics of interest in their

work.

For qualitative researchers, we envision this beliefs survey as another tool to enhance, not replace, interview and

observational data.

Housing the Beliefs Survey

This instrument has been designed to be loaded onto a web server either at a researcher’s site or on a

commercial server. Directions to those who oversee the running of the server are available.

Credits

This instrument is the result of many people’s efforts. Our research team first set out to determine the beliefs

we wanted to address, and we settled upon seven beliefs in three categories. Randy Philipp and Bonnie Schappelle

used these beliefs to develop the first draft of the beliefs instrument and directed the development of the instrument for

use on the World Wide Web. Rebecca Ambrose, Lisa Clement, and Jennifer Chauvot then undertook the immense

task of developing the rubrics for scoring the beliefs instrument, an undertaking that led to additional revisions to the

draft. Rebecca Ambrose assembled a group of visiting researchers to code our large-scale-study data; she and Lisa

Clement trained these coders and led the groups coding the data, leading to additional revisions to the instrument.

Final refinement of the beliefs instrument and organization of this manual were undertaken by Jason Smith, under

direction of Rebecca Ambrose. Bonnie Schappelle oversaw the final production of this manual. Randolph Philipp and

Judith Sowder served as the Principal Investigators of the grant that funded the work.

Server Requirements

Please note the following server requirements for installing the survey on your server:

The survey has been built using a series of Active Server Pages (ASP) scripts and HTML pages that use Microsoft FrontPageExtensions. The ASP scripts are written in the VBScript programming language. The survey must be run from a web server thatsupports both ASP and FrontPage Extensions. The two most common servers that support these are the Microsoft IISServer and the Microsoft Personal Web Server.

For the survey to run, Microsoft FrontPage Extensions must be loaded for the directory in which the survey is installed. Also, becausethe configuration files and the save files are in XML format, the Microsoft XMLDOM API must be available to parse and write the files.Two sets of videos have been provided. For users who complete the survey from an Apple Macintosh computer, a set of QuickTimevideos has been encoded. For users who complete the survey from a Windows PC, a set of Windows Media Videos (WMV) have beencreated. The Windows videos require Microsoft Windows Media Player version 6 or later (it is currently at version 8).

IIBrief History of Development

Beliefs-Survey Development

This instrument and the accompanying scoring rubrics were developed over a 2-year period by the authors. Six

other staff members contributed to the instrument’s development. We used a recursive cycle of development that

included designing segments, piloting them, analyzing student responses to the segments, revising the segments,

and piloting them again. We continued to consider whether our survey items were sufficient to assess each belief we

wanted to assess. The list of beliefs and the composition of the survey changed during our testing of several versions

of the survey and analysis of student responses.

The web-based survey was first used in Fall 2000 when it included one video segment with associated

questions; the platform enabled respondents to view the video in conjunction with the questions posed and to rewatch

the video if they wished. By Spring 2001, the video from the first version had been removed and three video clips had

been added to the survey. Early in 2001, all segments were in place; additional revisions were the refining of questions

related to each segment.

Five versions of the instrument were piloted on seven occasions (see table below for specific information about

administrations of the survey) so that during piloting, the survey was completed 205 times by 159 undergraduates. The

penultimate version of the survey was used at the beginning and end of a large-scale research study with 168

students, most undergraduates in their first mathematics course for teachers. For the final version of the survey, we

excluded one segment used in the large-scale study because the coding of this segment was found to be unreliable.

During piloting of the survey, we began to develop rubrics to analyze responses. Initially we categorized all

responses for each segment; we created a short characterization that captured the common features of the responses

for each category. Next we considered these characterizations for each segment in light of the belief it was designed to

assess; we ordered the categories from those that provided the most evidence for the belief to those that provided the

least evidence for the belief. While we piloted the segments and began to develop rubrics, we identified ways to adapt

the items to better elicit the beliefs to be assessed, also eliminating and adding items in the process of clarifying the

rubrics.

Most segments were in place for a pre/post pilot during the Spring 2001 semester; 29 students enrolled in the

mathematics course completed the survey at the beginning and end of the semester. Of these, 22 participated in the

treatment and the remaining 7 served as a control group. We used their responses to determine whether the survey

measured change. We compared changes in the treatment group with changes in the control group to ensure that the

survey measured the changes we expected to see as a result of the treatment. We also looked for variability

within the treatment group to ensure that the instrument captured the individual variability one would expect when 22

prospective teachers engage in the same experience.

The bulk of the instrument-development work at this point was focused on fine-tuning the rubrics, specifically

assigning scores to categories and clearly defining categories so that most responses would fit one and only one

category. One of the most important aspects of this work was testing for reliability. After a team refined a rubric and

developed a scoring system from a set of 20 responses, the team members individually applied that rubric to an

additional 30 responses to determine whether we would score them similarly. During our coding of these responses,

we encountered some coded differently by team members, so we discussed the issues raised and further clarified the

rubric.

For the purpose of validating the instrument, we asked 18 mathematics educators (7 professors and 11

mathematics education graduate students) to complete it. Their answers were coded by the coding team, and their

scores converged on the highest scores. We were convinced that our interpretations of the segments in the instrument

were compatible with those of other mathematics educators at other institutions around the country. The professors

believed the test to be a valid measure. One stated, “You can‘t observe 150 people working with children or studying

mathematics. Given the impossibility of seeing people in action to measure their beliefs, this instrument is a good

proxy” (personal communication, P. Kloosterman, June 2001).

Each belief was measured using two or three segments, so the last component of our work was to develop a

system for aggregating scores from individual rubrics to generate each overall belief score. The data used as a

reference for this task were from our pilot work. We developed our system, one that applies to each belief, mindful that

the scores are ordinal in nature. To our knowledge, this system is unique.

The survey represents countless hours of work on the part of a large team of people. We are convinced that is

the best survey possible given the constraints that we faced. The true test of its quality will be if other researchers find it

useful for their purposes. We believe that they will.

Coding Introduction

This section of the manual contains, first, the statement of the seven IMAP Beliefs the survey was designed to assess and, second, theCoding Navigator, a table with links to the scoring rubric for each belief and to the description of each segment rubric. The CodingNavigator is set up to show which rubrics are associated with each belief and to facilitate easy access to each belief rubric and to itsassociated segment rubrics. Within the table, just click on a Belief cell in the Coding Navigator to go to the manual page for the beliefscoring rubric or to a Segment cell to go to the page for the description of that segment.

The Rubrics of Rubrics follows the Coding Navigator. In the Rubrics of Rubrics document, Rebecca Ambrose explains how the scoresfor each segment were developed and then how those segment scores were combined to create a score for each belief.

Within the Belief Rubrics, a table for each belief shows how the segment scores are used to determine a score for the belief (click herefor the Belief 1 Rubric). Also, for each belief, we provide a table of the numbers and percentages of our participants who attained eachbelief score at the pre and post assessments (click here for the Belief 1 IMAP Results). These IMAP results are given for the 159 IMAPparticipants in our study.

Finally within the Segment Rubrics, we include the information coders will use for coding responses to each survey segment. Foreach segment rubric we provide (a) the Belief Statement and Rubric Description, (b) the Survey Item used in the segment, (c) anexplanation of how to determine Rubric Scores, according to the rubric, (d) a brief Scoring Summary for coders’ quick reference duringcoding, (e) Examples of responses that we have scored and the criteria on which we based each score, (f) Training Exercises andSolutions for the coders to use in learning to code the item responses with respect to the given belief, and, finally, (g) the IMAP Resultsfor that segment rubric—the numbers of our 159 participants who were assigned each of the possible rubric scores on both the pre andpost assessments. The links on this page are included so that the reader can quickly preview each element of the Segment Rubric for oneexample: B1-S3.2. Note that within the examples and training exercises for each segment rubric, the manual’s bookmarks areprovided to take one to each example and to each exercise. Therefore, coders who have access to the manual can complete the trainingexercises without having hard copies of these materials. And coders can use the bookmarks to quickly access each example or exercisefor discussion.

The Training Exercises for each segment rubric are arranged within two or three sets. The Set 1 exercises are ones that we consideredeasiest to code. The exercises in the last set are considered to be the most difficult of the examples and are lettered in reverse order. Forexample, for B1-S3.2, the Set 1 exercises are lettered A–H; the Set 2 exercises are lettered I–N; the final set, Set 3, exercises are letteredZ–U. The solutions are lettered in the same order as the exercises.

Belief About Mathematics

1. Mathematics is a web of interrelated concepts and procedures (and school mathematics should be too).

Beliefs About Learning or Knowing Mathematics, or Both

2. One’s knowledge of how to apply mathematical procedures does not necessarily go with understanding of theunderlying concepts.

3. Understanding mathematical concepts is more powerful and more generative than remembering mathematicalprocedures.

4. If students learn mathematical concepts before they learn procedures, they are more likely to understand theprocedures when they learn them. If they learn the procedures first, they are less likely ever to learn theconcepts.

Beliefs About Children's (Students') Learning and Doing Mathematics

5. Children can solve problems in novel ways before being taught how to solve such problems. Children in primarygrades generally understand more mathematics and have more flexible solution strategies than adults expect.

6. The ways children think about mathematics are generally different from the ways adults would expect them tothink about mathematics. For example, real-world contexts support children’s initial thinking whereassymbols do not.

7. During interactions related to the learning of mathematics, the teacher should allow the children to do as muchof the thinking as possible.

IMAP Web-Based Beliefs Survey1

Rubrics-of-Rubrics Overview

Rebecca Ambrose

For our Integrating Mathematics and Pedagogy (IMAP) Web-Based Beliefs Survey, we have developed 17 rubrics associated with

seven beliefs, two or three rubrics per belief. Each rubric was based on a scale appropriate for the responses for the relevant segments of the

instrument. We began our coding by examining the range of responses in the pilot data and categorized the responses according to type. For

a given belief, we next analyzed the level of evidence for holding that belief shown in responses within each category. A response was

scored 0 if we interpreted it as showing no evidence of the belief. The highest score possible for a given item indicated strong evidence of the

belief. Rubric-scale ranges were of 3 to 5 points, depending on the range of responses and the levels of evidence we identified in the

responses The more complicated prompts resulted in a wider range of scores. Five of our rubrics have scores 0–2, 11 rubrics have scores

0–3, and 1 rubric has scores 0–4.

The scores from this instrument are ordinal in nature. A response scored 3 on the basis of a rubric for a given belief indicates that we

interpreted the response as providing more evidence for that belief than one scored 2. The difference in level of evidence between scores of 2

and 3, however, varies from rubric to rubric, from large in some cases to small in others. Because of this ordinal nature of the scores, we

cannot appropriately sum the scores and discuss means for each belief. Instead we developed a more qualitative approach to collapsing the

data to assign overall scores for each belief.

To collapse the data, we developed a rubric-of-rubrics (ROR) system that we applied to each belief. To create the rubrics-of-rubrics,

we classified each score according to the degree to which we thought that it signified evidence for the belief. In assigning these designations, 1Preparation of this paper was supported by a grant from the National Science Foundation (NSF) (REC-9979902). The views expressedare those of the authors and do not necessarily reflect the views of NSF.

we considered the particular segments and the particular scores associated with the rubrics for scoring responses to those segments. In each

case the lowest score (0) was equated with No Evidence for the belief and the highest score (which varied by rubric) was equated with

Strong Evidence. The intermediate scores were equated with either Weak Evidence or Evidence. For example, the rubric for B7-S7 has a 4-

point scale, 0–3. On this scale 0 designates No Evidence; 1 designates Weak Evidence; 2 designates Evidence; and 3 designates Strong

Evidence. Many of the 4-point scales were treated in this fashion.

Some rubrics include a Weak designation whereas others skip from the No Evidence designation to the Evidence designation. For

example, on B3-S4 scores of both 0 and 1 designate No Evidence, because responses scored 1 provided only minimal evidence for the

belief. For this item, a score of 2, however, provided more than weak evidence and so designates Evidence. The reader may wonder why

we differentiated between responses scored 0 and 1 if neither includes evidence for the belief. We designed our rubrics to capture the full

range of responses we obtained and to differentiate among them. Some responses scored 0 were extreme and provided evidence that the

respondent held a belief in opposition to the belief under consideration, whereas responses scored 1 were not extreme but still lacked

evidence for the belief. We use the rubrics not only for the rubric-of-rubrics analysis described here but also for other purposes, for which

the difference between scores of 0 and 1 score are important.

We assigned a Weak designation to responses that showed either minimal evidence for the belief or evidence in contradiction to the

belief. Some items on the instrument prompted respondents to create responses that revealed their ambivalence about the issue. For example,

in Segment 7 the respondents were asked to react to a teaching episode and then to identify the weaknesses in the teaching. Some

respondents pointed out that the guidance provided by the teacher was skillful and then, in responses to subsequent prompts, went on to

point out that the guidance provided by the teacher was excessive. We interpreted this ambivalence as weak evidence of the belief that

teachers should allow their students to do as much mathematical reasoning as possible.

After designating levels of evidence from No Evidence to Strong Evidence for each score described by each rubric, we used these

designations to develop two scoring systems to apply to our belief instrument: one system for beliefs measured using two rubrics and

another system for the beliefs measured using three segments. Each system was modified to fit the specifics of the related rubrics, for

example, to accommodate differences between 4-point rubrics that included a Weak designation and those that did not.

The scores on the rubrics-of-rubrics that are based on three rubrics range from 0–4 and are again ordinal, not interval, scores.

Respondents scoring 0 are thought not to hold the belief because they provided little or no evidence that they do. Those scoring 4 are thought

to hold the belief strongly because they provided strong evidence of the belief in the majority of responses assessing it. People receiving

scores of 1–3 showed some evidence of having the belief, but the evidence was inconsistent. For example, most people who scored 1

provided no evidence for the belief on at least one segment and some evidence in another, but the balance of the responses was toward No

Evidence. For the score of 2, the balance tipped toward Evidence, but some scores on some rubrics were for Weak Evidence. Combinations

that included at least one Strong Evidence and had Strong Evidence/Evidence scores that far outweighed the Weak Evidence/No Evidence

scores were scored 3.

One challenge we faced in developing our system was to assign scores to combinations of responses that were unexpected: responses

that showed no evidence of a belief in one segment, evidence for that belief in another, and strong evidence in a third. In the case of Belief 7,

we decided that a 0 based on one rubric indicated that the respondent did not hold the belief, so regardless of the score on the other segment,

the respondent was given a score of 0 for the belief (as indicated by the *s in Table 1). In most cases, these seemingly inconsistent scores

were for responses to items situated in mathematically different contexts. For example, the belief that one's knowledge of how to apply

mathematical procedures does not necessarily go together with one's understanding of the underlying mathematical concepts might be evident

in a response about the standard algorithm for subtraction but not in the response on division of fractions. In these cases we assigned an

overall score by assessing the strength of the belief according to the number of times it was evident. Using our system, we could treat such

cases consistently across beliefs. For example, a respondent receiving designations of Weak Evidence, Weak Evidence, Evidence for any

given belief would always receive a score of 2 for that belief.

A few anomalies in our system require justification. In some instances a 1-point change from applying a single rubric can result in a

2-point change in the rubric of rubrics. For example, scores of 0, 1, 2 for Belief 2 receive a score of 1 on the rubric of rubrics, whereas

scores of 0, 2, 2 for Belief 2 receive a score of 3, although the two sets of scores differ only by 1 point in the middle score. The middle score

derives from a segment with three scores, 0, 1, and 2, with designations of No Evidence, Weak Evidence, and Strong Evidence (no score is

associated with Evidence for this segment). The 0, 1, 2 scores thus have an NWS designation whereas the 0, 2, 2 scores have an NSS

designation. The lack of an Evidence designation for the segment gives rise to the 2-point change. Our system has few such anomalies,2 each

of which can be justified. A designation skip indicates a large difference between two scores, enough difference to warrant the skip.

General Rubric of Rubrics

In reviewing our system, we were tempted to change a few scores, but after we revisited the data and saw the implications for changing these

scores, we were convinced that they should not be changed.

B1-S3.2Rubric for Belief 1—Segment 3.2

Belief 1

Mathematics is a web of interrelated concepts and procedures (and school mathematics should be too).

Description of Rubric

We operationalized this belief by thinking of a web of interrelated concepts and procedures as consisting of nodesand the connections among them. For this rubric, the nodes are the five strategies whereas statements about therelationships between strategies represent the connections between nodes. The number of strategies arespondent chooses to share is thus one factor in determining a respondent’s score. For example, if a respondentchooses to share two or fewer strategies, she receives the lowest score on the rubric, regardless of herexplanations for wanting to share the strategies. We reasoned that even if a respondent makes a connectionbetween two strategies, she still does not value the web-like nature of mathematics if she has chosen to share onlytwo strategies. Therefore, to receive higher scores on the rubric, respondents must choose to share three or morestrategies. For example, to receive the second-highest score on the rubric, a respondent must choose to shareeither four or five strategies and must value all or most of them. Further, to receive the highest score on the rubric,a respondent must choose to share ALL the strategies, make comments to indicate that she values each strategy,and make at least one explicit connection among strategies. This last criterion (that a respondent makes an explicitconnection among strategies) addresses the interrelationship between concepts and procedures (or theconnections between the nodes).

Carlos149 + 286

Written on paper

Henry149 + 286

Henry says, "I know that 40 and 80 is 120, and one hundred and two hundred makes 300, and 120 and 300 is 420, and 9 and 6 is 14, so 420 and 10 is 430, and 4 more is 434."

Elliott149 + 286

Written on paper

Sarah149 + 286

Sarah says, "Well, 149 is only 1 away from 150, so 150 and 200 is 350, and 80 more is 430, and 6 more is 436. Then I have to subtract the 1, so it is 435."

MariaManipulatives

= 100Called a flat

= 10Called a long

= 1Called a single

Maria uses manipulatives (base-ten blocks) to solve the problem. Maria says, "I took one flat for the 100 in 149 and 2 flats for the 200 in 286.

I took 12 longs: 4 for the 40 in 149 and 8 for the 80 in 286.

I took 15 singles for the 9 in 149 and the 6 in 286.

Then I counted like this, '100, 200, 300'; then for the longs, '310, 320,

B1-S3.2Rubric Scores

0. Responses scored 0 indicate no appreciation for the interconnectedness of procedures and concepts. A decision to shareonly one or two strategies is interpreted as evidence of this lack of appreciation. Such respondents tend to express a definitepreference for Carlos's strategy.

1. Responses scored 1 indicate little appreciation for the interconnectedness of concepts and procedures. Despite the numberof strategies the respondent wants shared, the supporting explanations give little or no indication that the strategies areconnected. The explanations for wanting to share tend to show little appreciation for having multiple approaches to solveproblems. Many people who score 1 also have a definite preference for Carlos’s strategy.

2. Responses scored 2 indicate a valuing of multiple ways to understand big ideas in mathematics. They may indicate thatsome procedures and concepts are interconnected, although often the connections are not explicit. Most or all strategies inaddition to Carlos's are valued, and reasonable appreciation tends to be expressed for the strategies. However, a score of 2differs from 3 because those scoring 2 tend not to write about the interconnectedness of the strategies.

3. Responses scored 3 indicate appreciation for the interconnectedness of concepts and procedures and valuing of multipleways to understand big ideas in mathematics. Respondents would have students share all strategies, and they tend to havemathematically appropriate reasons for the sharing; they indicate that they value all strategies. Some of their explanationssupport the idea that mathematics is a web. That is, students who score 3 write about the connections between (and among)at least some strategies. A response scored 3 differs from one scored 2 because of the explicit mention of the mathematicalconnections among strategies. Also, one scoring 3 does not state a preference for Carlos's strategy.

Comments on Scoring

*Note one exception to the number of students who share: A participant states that Carlos's strategy should not beshared. For purposes of using the rubric, we count this preference not to share Carlos’s strategy as a shared strategy(Carlos exception), because most reasons for choosing not to share Carlos’s strategy show evidence of this belief.Similarly, do not count as negative any responses that indicate that Carlos may not understand his strategy.

Yes This is thetraditionalalgorithm,which childrenare likel tohave seen inschool or athome. Itprovides anelegant andconcise way torecord aprocedure.Doing theprocedurecorrectly doesnot ensureunderstanding,but havingCarlos presentthe procedurewould providean avenue forconnecting hismethod,Elliott'smethod, andMaria'smethod.

Yes Henry ismaking use ofplace valueand facts thathe knows inorder to solvethe problem.His solutionshows thatyou do nothave to starton either theleft or theright.Breaking 14into 10 and 4shows someplace valueunderstanding.

Yes Elliott'smethodshows anunderstanding of placevalue and thecommutativityof addition. Itis a methodthat is likely tobe easilyaccessible tootherchildren. Itconnectsnicely toCarlos, Henryand Maria'smethods.

Yes Sarah'smethod maynot beunderstoodby all of theotherchildren, but Iwould stillwant her toexplain itbecause itwould makesense tosomechildren. Itshows amental mathway ofthinking aboutthe problemby usingcompensation. I wouldwant otherchildren tosee theflexible way ofthinking thatis involved.

Yes Maria's solutionprovides aconcreterepresentationof the placevalues and canbe inspectedfrom severalangles. It couldbe used toaugmentCarlos, Henry,and Elliott'ssolutions bydoing thecounting indifferent ways.Maria's methodis bothkinesthetic andvisual andprovides aconcreterepresentationof the problemand thesolution.

Rubric for Belief 1—Segment 3.3

Belief 1

Mathematics is a web of interrelated concepts and procedures (and school mathematics should be too).

Description of Rubric

Respondents are explicitly asked to select an order in which they would focus on strategies if they were to teacha place-value unit, and then they are asked to explain their order. Because they are asked to provide oneexplanation for their order (instead of explaining each strategy in turn), the item lends itself to writing aboutconnections among and between strategies. So, if respondents make no connections between or amongstrategies, they receive the lowest possible score on this item. Furthermore, to receive the highest score on theitem, a respondent must choose to share at least four strategies AND make at least two statements thatexplicitly connect the strategies with one another. We take these connecting statements as proxies for therespondent’s belief about the interrelatedness of concepts and procedures.

We also look for conceptual statements made about the individual strategies to identify respondents who mayrecognize the conceptual benefits of a strategy but do not explicitly connect those strategies to other strategies.Respondents who have two such responses receive the middle score. Within this item, we score the web-likeaspect of mathematics by examining the number of strategies on which the respondent chooses to focus whileteaching the place-value unit. Although respondents could choose to share all five strategies and still receivethe lowest score because of the lack of mathematical connections mentioned in their explanations, scores arecapped based on the number of strategies selected. For example, if respondents choose to focus on one or twostrategies, they receive the lowest score; if respondents choose to focus on exactly three strategies, they receiveeither the lowest or middle score; and if the respondents choose to focus on four or five strategies, their scoresare based on their explanations.

Henry says, "I know that 40 and 80 is 120, and one hundred and two hundred makes 300, and 120 and 300 is 420, and 9 and 6 is 14, so 420 and 10 is 430, and 4 more is 434."

Sarah says, "Well, 149 is only 1 away from 150, so 150 and 200 is 350, and 80 more is 430, and 6 more is 436. Then I have to subtract the 1, so it is 435."

Rubric Scores

0. Responses scored 0 do not indicate the belief that mathematics is an interrelated web of concepts and procedures. Inparticular, they do not mention connections among strategies, nor do they mention the concepts related to particularstrategies. Respondents may indicate that they chose an easiest-to-most-difficult progression, without stating why onestrategy is easier than another, or they may make no conceptual connections within or among the strategies. Somerespondents who score 0 may make one statement about how a strategy is related to a concept, but the statement istypically about the usefulness of manipulatives and does not go beyond that usefulness.

1. Responses scored 1 indicate a beginning view of mathematics as an interrelated web of concepts and procedures.Respondents describe connections between mathematical concepts and the strategies to justify the order in whichthey would have students share strategies. Some may even mention two connections between strategies, butbecause they want students to share only three strategies, the web that they have created is considered sparse.

2. Responses scored 2 indicate a view of mathematics as an interrelated web of concepts and procedures withdescriptions of connections between strategies. Because these respondents want to share at least four strategies,the view of mathematics as a web is more expansive than the view of someone who scores 1.

Comments on Scoring

A concept-within-a-strategy connection is a statement about one particular strategy; the statement indicates whylearning the strategy would be useful, conceptually (e.g., “I would share Sarah's method because she uses numbersense to solve it” or “Maria's method shows place value with the blocks.”).

A strategy-to-strategy connection is a statement about two or more strategies; the statement explicitly indicates that thestrategies are related in some way: “Maria's solution is the most basic and allows the use of manipulatives; Elliott'stakes away the manipulatives but uses the same method to solve the problem.” In this case, the respondent makes aconnection between Maria’s and Elliott’s strategies by mentioning that the approaches are the same although the toolsused are different.

Coders should treat a respondent’s selection of “No Preference” the same as “I don’t want to share any others.”

Henry's strategy would be a good followup because he also simplifies the problem byadding the tens with the tens the ones with onesand the hudreds with hundreds, it's actuallypretty much the same problem. Carlos's strategywould be next because it is essential that theylearn to "carry over" numbers. Carlos's strategyis the most commonly known/used. FinallyMaria's.

first I would share marias strategy because, like isaid, its visual, and it would really help the kidsunderstand how addition works, how ten longsequal a flat and how ten singles equal a long,which explains the "carrying part" so then, theywould be ready for Carlos' s method, and wouldunderstand why it is that they carry a number.and finally, elliots way, in this method, there is nocarrying, and is very straighforward, the kidswould enjoy it. i wouldnt teach henry's becauseits a repetition of Elliott and i wouldnt teachsarahs because i think it could cause confusion.

Elliott's, Henry's, and Sarah'sthinking are all somewhat similiar, and are variousways of solving the problem in one's head.Carlos's thinking is best saved until the end,when the children already understand placevalue, and then the algorithm will be of moreimportance and value to them.

Although this response sounds web-like, the response is too global to score higher than 0.The respondent does not mention how particular strategies are connected with one anotherand does not mention the concepts within the strategies (one could give the respondent creditfor the global connection of place value to strategies, but the response would still score 0).

Rubric for Belief 2—Segments 3.4 and 3.5

Belief 2

One’s knowledge of how to apply mathematical procedures does not necessarily go with understanding of theunderlying concepts.

Description of Rubric

This item is set in the context of analyzing three students’ strategies for adding 149 plus 286. Carlos uses thestandard algorithm taught in the United States to solve the problem. Elliott uses an expanded algorithm: He firstadds the hundreds, then the tens, and then the ones, before totaling the three partial sums. Sarah uses acompensating strategy in that she adds 150 and 200, then 80 more, then 6 more, and then subtracts 1, to makeher sum equal to the sum of her original numbers, 149 +286. The respondents are asked whether Carlos coulduse and explain Elliott’s strategy (Item 3.4) and whether Carlos could use and explain Sarah’s strategy (Item 3.5).This item is presented to determine whether the respondent states that an individual may be able to perform aprocedure (such as the standard addition algorithm) but may not understand the underlying mathematical concepts(such as the place-value concepts one must understand to appropriately use the expanded addition algorithm andthe compensating strategy).

The highest score on this rubric goes to respondents who recognize that Carlos may not be able to use Elliott’s orSarah’s strategies, because Carlos may have only procedural knowledge, whereas the other two strategies requiresome understanding of the underlying place-value concepts. In contrast, the lowest score on this rubric goes torespondents who state that if Carlos can perform the standard algorithm, then he can likewise use the other twostrategies.

The scoring system for this rubric is different from the system for most rubrics in that scorers first score Items 3.4and 3.5 separately using the Scoring Summary Table and then use a second table to determine an overall scorethat is based on the pair of scores.

Carlos149 + 286

Written on paper

Henry149 + 286

Henry says, "I know that 40 and 80 is 120, and one hundred and two hundred makes 300, and 120 and 300 is 420, and 9 and 6 is 14, so 420 and 10 is 430, and 4 more is 434."

Elliott149 + 286

Written on paper

Sarah149 + 286

Sarah says, "Well, 149 is only 1 away from 150, so 150 and 200 is 350, and 80 more is 430, and 6 more is 436. Then I have to subtract the 1, so it is 435."

MariaManipulatives

= 100Called a flat

= 10Called a long

= 1Called a single

Maria uses manipulatives (base-ten blocks) to solve the problem. Maria says, "I took one flat for the 100 in 149 and 2 flats for the 200 in 286.

I took 12 longs: 4 for the 40 in 149 and 8 for the 80 in 286.

I took 15 singles for the 9 in 149 and the 6 in 286.

Then I counted like this, '100, 200, 300'; then for the longs, '310, 320,

Overall Rubric Scores

0. Responses scored 0 indicate that children who are able to perform procedures correctly understand the concepts thatunderlie the procedures OR show no evidence that Carlos may have gaps in his understanding. Respondents suggest thatchildren who can solve addition problems using the standard algorithm can seamlessly solve addition problems usingmethods that require understanding of place value. However, some who score 0 may state that the student who uses thestandard algorithm would be unable to solve problems using the other methods because the other methods are invalid or tooconfusing.

1. Responses scored 1 also tend to indicate that children who are able to perform procedures correctly understand conceptsthat underlie the procedures. However, the respondent may also suggest that a child who can solve an addition problemusing the standard algorithm may be unable to solve the same problem using the alternative strategies because thealternatives are too different, instead of because they are more conceptual. They may state that Carlos could solve andexplain a problem using Elliott's method but that Sarah's is too different for Carlos to be able to use.

2. Responses scored 2 may indicate that one's knowledge of how to apply mathematical procedures does not necessarily gotogether with one's ability to solve problems in multiple ways. Respondents in this group tend to acknowledge that childrenwho can perform procedures may not be able to solve problems using alternative strategies, but at least one of theexplanations is poorly developed. A typical response scored 2 might indicate evidence of the belief in 3.4 but not in 3.5.

3. Responses scored 3 show respondents’ understanding that children who are able to perform procedures correctly may notunderstand underlying concepts. They include reasonably well-developed explanations to support this belief in both 3.4 and3.5. A 3 differs from a 2 because both responses tend to indicate that Carlos may have procedural, but not conceptual,understanding.

Rubric for Belief 2—Segment 4

Belief 2

One’s knowledge of how to apply mathematical procedures does not necessarily go with understandingof the underlying concepts.

Description of Rubric

The focus of this rubric is on what the respondent states about Lexi’s work and whether Lexi understandswhat she is doing when she correctly executes the standard algorithm for subtraction. Respondents whonote that she may not understand what she is doing are providing evidence of the belief. Somerespondents note that Lexi’s way (the standard subtraction algorithm) is difficult to understand BUT, thisrealization is NOT equivalent to saying that when Lexi executes the algorithm correctly, she may notunderstand what she is doing. Coders, in initially using this rubric, often mistake comments about thedifficulty of understanding the algorithm for evidence of this belief.

Learning this rubric can be difficult, but once it is learned, coding is fairly easy and reliability should berelatively high. Contributing to the rubric’s difficulty is the fact that we did not ask directly, “Does Lexiunderstand what she is doing?” We avoided direct questions of this sort because we were assessingbeliefs rather than knowledge.

Pertinent responses for the belief are usually in Items 4.3, 4.7, or both, although evidence can be found inother parts of the segment. Read the entire response to ensure that all relevant aspects of the responseare considered.

4. Here are two approaches that children used to solve the problem 635 – 482.

Lexi 5613 5 – 4 8 2 1 5 3 Lexi says, "First I subtracted 2 from 5 and got 3. Then I couldn't subtract 8 from 3, so I borrowed. I crossed out the 6, wrote a 5, then put a 1 next to the 3. Now it's 13 minus 8 is 5. And then 5 minus 4 is 1, so my answer is 153."

Ariana

635 – 400 = 235235 – 30 = 205205 – 50 = 155155 – 2 = 153 482

Ariana says, "First I subtracted 400 and got 235. Then I subtracted 30 and got 205, and I subtracted 50 more and got 155. I needed to subtract 2 more and ended up with 153."

4.1 Does Lexi's reasoning make sense to you?

Yes No

4.2 Does Ariana's reasoning make sense to you?

Yes No

4.3. Which child (Lexi or Ariana) shows the greater mathematical understanding?

Question 4 (continued)

Here are those two approaches again so that you can refer to them to finish this section.

Lexi 5613 5 – 4 8 2 1 5 3 Lexi says, "First I subtracted 2 from 5 and got 3. Then I couldn't subtract 8 from 3, so I borrowed. I crossed out the 6, wrote a 5, then put a 1 next to the 3. Now it's 13 minus 8 is 5. And then 5 minus 4 is 1, so my answer is 153."

Ariana

635 – 400 = 235235 – 30 = 205205 – 50 = 155155 – 2 = 153 482

Ariana says, "First I subtracted 400 and got 235. Then I subtracted 30 and got 205, and I subtracted 50 more and got 155. I needed to subtract 2 more and ended up with 153."

For the remaining questions, assume that students have been exposed to both approaches.

Rubric Scores

0. Responses scored 0 indicate that Lexi’s correct execution of the procedure shows that she understands the procedure.Respondents may think that Ariana has the better understanding, but in their analyses of Lexi’s work, they give noindication that Lexi may not understand what she is doing.

1. Responses scored 1 include minimal evidence that Lexi may not understand. The respondents may provide a hint ofLexi’s not understanding when they discuss Ariana’s strategy. However, they directly state neither that Lexi doesunderstand nor that she may not understand. In contrasting Lexi’s and Ariana’s approaches, they indicate that Ariana hasunderstanding and that Lexi can get a correct answer. Without stating that Lexi may not understand, they imply, in the waythat they set up the contrast, that she may not.

2. Responses scored 2 show clear evidence of skepticism about Lexi’s understanding. Respondents state at somepoint—in commenting on which student has the better understanding, in considering whether students will be successfulusing Lexi’s approach, or in discussing which approach they would like their students to use—that Lexi may notunderstand.

B2-S8

Rubric for Belief 2—Segment 8

Belief 2

One’s knowledge of how to apply mathematical procedures does not necessarily go with understanding of the underlyingconcepts.

Description of Rubric

In Item 8.1, the respondents rank four fraction items, including “Understanding 1/5 X 1/8,” in terms of their relative difficultiesand explain their ranking. This rubric is based on Item 8.4, in which respondents are asked to respond to the question “Inquestion 8.1, we asked you to rank the difficulty of understanding 1/5 x 1/8. By understand, were you thinking of the ability toget the right answer? [Select yes or no]. Please explain your response.” In the latter item, the respondents discuss what theythink “to understand multiplication of fractions” means. We interpret their responses to the two items as providing confirmingor disconfirming evidence of this belief according to whether the respondents (a) consistently draw distinctions betweenunderstanding fraction multiplication and performing procedures (highest score) or (b) conclude that a student who canperform a procedure understands it (lowest score). Middle scores go to two types of respondents: (a) those who provideclear evidence of the belief in one item but disconfirming evidence of the belief in the other item (we consider that theserespondents hold the belief, albeit fragilely; that is, although they provide evidence of the belief in one item, it is context-dependent in that they will provide disconfirming evidence of the belief on another item); (b) those who provide vagueresponses to both items so that determining whether these respondents provide confirming or disconfirming evidence of thebelief is difficult.

Respondents who receive the lowest score may fail to recognize that understanding fraction multiplication requires more thanperforming a procedure. Such respondents may view mathematics as following rules without reason. This response differsfrom the response of one who states that anyone who can perform the procedure of fraction multiplication must necessarilyunderstand the underlying concepts of that procedure. In our scoring, however, we score both these types of responses 0.The reliability on scoring this rubric tends to be lower than on most rubrics, because the scorers must interpret the languageused and sometimes make inferences not required in other rubrics. The readers are advised to spend extra time discussingall examples and training exercises carefully, discussing aloud their rationales for the scores they have given.

Rubric Scores

0. Responses scored 0 indicate that respondents think of only the procedure for multiplying fractions although they are asked torank the item on the difficulty of understanding 1/5 X 1/8. In their responses, these students do not distinguish betweenability to perform this procedure and understanding of the underlying concepts.

1. Responses scored 1 show some recognition that ability to perform procedures does not necessarily indicate understanding ofunderlying concepts, but this distinction is fragile. That is, the respondents may mention conceptual understanding in onepart of the response but mention only procedures in a different part.

2. Responses scored 2 indicate that understanding of the underlying concepts does not necessarily follow from ability toperform procedures. The respondents consistently distinguish between understanding concepts and performing procedures.

• Either 8.1b or 8.4 is too vague to interpret, AND the other response indicates that the student is (a) thinkingof conceptual understanding OR (b) making a distinction between conceptual and procedural understanding[concepts, vague].

• Responses to both 8.1b AND 8.4 indicate that the student is (a) thinking of conceptual understanding OR(b) making a distinction between conceptual and procedural understanding [concepts, concepts].

Comments on Scoring

The words vague, concepts, and procedures in the brackets above are to help the scorer label each response separatelyand then find the rubric score. For example, if the response in 8.1b is vague and the response in 8.4 mentions onlyprocedures, then the overall response is labeled [procedures, vague] and, thus, is scored 0. If the response in 8.1bincludes either mention of conceptual understanding or a distinction between procedures and concepts and the responsein 8.4 is vague, then the overall response is labeled [concepts, vague] and, thus, is scored 2.

Rubric for Belief 3 — Segment 4

Belief 3

Understanding mathematical concepts is more powerful and more generative than remembering mathematicalprocedures.

Description of Rubric

This rubric is designed to assess whether the respondent believes that Ariana’s conceptual approach will bemore generative than Lexi’s algorithmic approach. By a generative approach we mean one that is used withgreat success and gives rise to future conceptual development. One indicator of this belief, in our interpretation,is the success rate that respondents predict for the two approaches. Respondents who expect a highersuccess rate for those using Ariana’s approach are seen as providing some evidence of the belief. Anotherindicator of this belief is which strategies the respondent would like to have children in his or her classroom use.Those who would like Ariana’s approach used indicate that they perceive this to be a generative strategy. Therespondent’s choice of the child having the greater understanding was used only to discriminate between thetop two scores.

Our reliability in coding for this rubric was high because coding is fairly objective. Occasionally a respondent’scomments contradict her response to another question. In these cases a more subjective analysis is in order,and the coder must consider which response to use in coding.

4. Here are two approaches that children used to solve the problem 635 – 482.

Lexi 5613 5 – 4 8 2 1 5 3 Lexi says, "First I subtracted 2 from 5 and got 3. Then I couldn't subtract 8 from 3, so I borrowed. I crossed out the 6, wrote a 5, then put a 1 next to the 3. Now it's 13 minus 8 is 5. And then 5 minus 4 is 1, so my answer is 153."

Ariana

635 – 400 = 235235 – 30 = 205205 – 50 = 155155 – 2 = 153 482

Ariana says, "First I subtracted 400 and got 235. Then I subtracted 30 and got 205, and I subtracted 50 more and got 155. I needed to subtract 2 more and ended up with 153."

Question 4 (continued)

Here are those two approaches again so that you can refer to them to finish this section.

Lexi 5613 5 – 4 8 2 1 5 3 Lexi says, "First I subtracted 2 from 5 and got 3. Then I couldn't subtract 8 from 3, so I borrowed. I crossed out the 6, wrote a 5, then put a 1 next to the 3. Now it's 13 minus 8 is 5. And then 5 minus 4 is 1, so my answer is 153."

Ariana

635 – 400 = 235235 – 30 = 205205 – 50 = 155155 – 2 = 153 482

Ariana says, "First I subtracted 400 and got 235. Then I subtracted 30 and got 205, and I subtracted 50 more and got 155. I needed to subtract 2 more and ended up with 153."

Rubric Scores

0. Responses scored 0 indicate that remembering the standard procedure Lexi uses will be more generative than using Ariana’sconceptual approach. Respondents state that children will be successful when using the procedure. They state that Ariana’sapproach is confusing and that children will be unsuccessful when using it. They want children to use the standard algorithm andavoid Ariana’s approach.

1. Two types of responses are scored 1. Respondents who state that children will be nearly equally successful in using Ariana’sand Lexi’s approaches but prefer that children use Lexi’s score 1. Although they acknowledge that students might use Ariana’swith success, our interpretation is they do not see her approach as powerful because they do not want their students to use it.Some see Ariana’s as the back-up strategy for students who cannot learn the standard algorithm, instead of seeing it as the morepowerful of the two approaches.

The other respondents who score 1 state that children using Lexi’s approach will be more successful than those using Ariana’s.Some of these respondents are impressed with Ariana’s strategy and state that it is quite difficult. They do not, however, indicatethat the conceptual approach is more generative and powerful than the standard procedure. They would allow the conceptualapproach to be used in their classrooms (along with the procedure), indicating that they see it as having some power orgenerativity.

2. Two types of responses are scored 2. Respondents who choose either Lexi or Ariana as having the better understanding andthink children using these strategies will be equally successful score 2. They see the conceptual approach as being equivalent inpower and generativity to the standard algorithm. They would like to have both approaches in their classroom, often stating thatone approach will suit some students whereas a different approach will suit other students.

The other response that is scored 2 is from those who choose Lexi as having the better understanding but state that children willbe more successful in using Ariana’s approach than in using Lexi’s. Thus, they suggest that the standard algorithm is morepowerful than the conceptual approach, but they also see the conceptual approach as being generative. They also would likeboth strategies to be used in their classroom, and some state that Ariana’s approach should precede Lexi’s.

3. Responses scored 3 indicate that Ariana has the better understanding and that children will be more successful using herapproach than using Lexi’s. Some respondents prefer that children use Ariana’s; others would allow both. These responsesshow strong evidence that the conceptual nature of Ariana’s approach will be powerful and generative. Some respondents notethat Ariana thinks about the whole quantity instead of thinking about the digits separately, as Lexi does.

Comments on Scoring

In answering Items 4.7 and 4.9, respondents sometimes fail to recognize that the number they select is meantto be out of 10 students and think that it is out of the number of children they predicted (in 4.6 and 4.8,respectively) would choose the strategy. Their error is usually obvious to the coder. Looking at the numbers ishelpful, but be careful in doing so.

B 0Indicates that Ariana has the better understanding but that her strategy is more complicated andthat children will have trouble using it. Conceptual approach is not noted as being moregenerative for children.

C 2The two approaches are considered to be about the same in terms of ease of execution, andboth approaches will be allowed in the classroom.

D 1 Lexi’s is considered the easier approach, but Ariana’s is given “air time.”

G 3Ariana’s way preferred in the classroom. Children will be more successful when using it, and itshows better understanding.

H 2

Success rates for the two strategies will be about the same (they are within 1); respondent isinterested in having students use both approaches. Her interest in beginning instruction withLexi’s strategy is troubling, but this aspect reflects a different belief (the timing of teachingconcepts and procedures).

I 2Type 2(B) response—Ariana’s approach is seen as being easier than Lexi’s (90% success ratevs. 70%), and both strategies will be allowed in the classroom. Because Lexi is chosen as thestudent with the better understanding, the response is scored 2.

J 1

Could be scored 0 or 1(B). Going strictly by the 4.9 response, one would score it 0. However,the respondent states interest in having her students acquainted with Ariana’s approach; thus itcould be scored 1. The respondent provides some appreciation for the generativity of concepts,so we scored the response 1.

K 0Lexi’s approach is considered the better strategy throughout. The respondent expresses noappreciation for the conceptual nature of Ariana’s approach.

L 3

Ariana has better understanding. Children will be more successful when using Ariana’sapproach, and children will be encouraged to use both strategies in the classroom. All thewritten comments support the view that Ariana’s conceptual approach will be more generativethan the standard algorithm.

Z 3Ariana’s is considered the superior strategy throughout. The 7 (q4.7) and 8 (q4.9) are close insize, but the other comments indicate that the respondent thinks that the concepts will begenerative.

B3–S4

Exercise Score Comment

Y 2Appreciation shown for Ariana’s approach, but respondent thinks that children will be equallysuccessful using either method.

X 2

This response is difficult to code because the respondent is unsure whether she understandsAriana’s strategy. She seems to think that understanding is generative: She is willing to haveboth strategies shared and notices the limitations of Lexi’s. With little to go on with thisresponse, we gave her the benefit of the doubt.

W 0Lexi’s approach is considered easier. The conceptual nature of Ariana’s approach is notapparent to the respondent.

V 1We can go only by the numbers in this response; the written comments provide little information.The respondent seems to think that children will be more successful when using Lexi’s but iswilling to have Ariana’s used by her students.

U 3

Ariana’s is considered the superior strategy throughout, as an easy strategy that can beunderstood. The comment that “it is because the students do not understand why they are doingit . . . so they can make easy mistakes” is interpreted as strong evidence that the respondentthinks that understanding concepts is more generative than memorizing procedures.

Rubric for Belief 3––Segment 9

Belief 3

Understanding mathematical concepts is more powerful and more generative than remembering mathematical procedures.

Description of Rubric

The focus of this rubric is on what kind of instruction the respondent suggests so that more children will be successfulwith division of fractions in the future. Respondents who emphasize the role of practice do not provide evidence thatthey believe conceptual understanding is more generative than memorizing procedures. Those who note the difficultyof remembering what is not well understood provide evidence that they believe in the generativity of conceptualunderstanding.

Coders should first examine responses to 9.5 and 9.6, the responses that provide most of the information related tothis rubric. Scanning the answers in 9.1–9.4 will help to determine whether the respondent emphasizes theimportance of understanding. Some make recommendations about what the teacher should have done in theirresponses to 9.1 and 9.4. Responses to 9.3 are important only for distinguishing between scores of 2 and 3.

Rubric Scores

0. Responses scored 0 indicate that the girl knows the steps and that such knowledge is adequate. The respondentsrecommend that she practice more. They may state that she does not understand, but they do not recommend that theteacher do something to promote understanding. They do not show evidence of thinking that concepts are moregenerative than procedures, because they do not suggest that the teacher should focus on the concepts rather than theprocedure. Their responses are focused on the role of repetition in helping children remember procedures and mayinclude suggestions about mnemonic aids like songs, acronyms, or chants.

1. Responses scored 1 indicate that this girl does not understand and needs an explanation AND more practice. (Weinterpret such statements as indicating that the respondents value both memorization and understanding.) Theseresponses do not indicate that understanding is more helpful than memorization for remembering mathematics.

2. Responses scored 2 indicate that the child does not understand but that the child will be able to solve the problem in afew days. We interpret this response as indicating that procedures can be easily learned and remembered. When theserespondents see that the child was unsuccessful, they recant and state that most children will not remember if they do notunderstand. They state that the teacher needs to act to promote understanding.

3. Responses scored 3 indicate that the child does not understand and that because of this lack of understanding, the childwill not be able to solve the same problem in a few days. They indicate that most children will not retain information theydo not understand and that the teacher must act to promote understanding. We interpret these responses as strongevidence of the belief that with conceptual understanding, children (not only some children) will be able to solve problemswithout having to memorize; throughout these responses, the importance of understanding is emphasized.

No She mayremembersome steps ofthe formula,but until sheclearlyunderstandswhy she isdoing whatshe is doing,she won't beable to solvesimiliarproblems,especially ifthey are just alittle bitdifferent thanthe ones thatshe had beentaught tosolve with thealgorithm.That alwaysthrows a childoff track,when theproblem theyneed to solveis differentthan the onesthey learnedhow to solvewith thealgorithm,unless theyclearlyunderstandmathematicallywhy they aredoing whatthey aredoing.

That was what Ithought wasgoing tohappen. Thechild had beenable to repeatwhat theteacher haddone the daybefore, withoutanyunderstanding,like a robot.But when shehad to comeback the nextday, she didn'tknow what todo, or why todo it. It hadjust beennumbers and aformula to her,notunderstanding

20 I thinkthat somechildrenwouldrememberwhat todo, justbecausethey mayhave agoodmemory.Othersmay justtake agoodguess andbe able tosolve it.

I think the teacherwould need to usesome visual aidsand drawings to getthe children tobetter understand it.Even when I was achild, before I tookmy Math 210 class,I used to makedrawings to try tofigure out how tosolve mathproblems. That waswhat worked bestfor me, and wouldprobably work bestfor at least someother children. Shecould use real lifeexamples, but notword problemswritten down onpaper yet, and havethem solve thosereal life problems.Then the teacherneeds to relate thereal life problems tothe ones on thepaper. If she canclearly get acrossthe message as towhy the children aredoing what they'redoing, I think thatthey wouldunderstand and beable to solve similiarproblems in thefuture.

A 2Respondent mentions lack of understanding in 9.2 and 9.5. Her meaning for “give them alittle story behind their understanding” is unclear, but we assumed that she wanted thestudents to have some conceptual understanding.

B 1 This is a classic example of an “explain and practice” sort of response.

C 0Another classic; respondent suggests that practice will ensure success on this type ofproblem.

D 3

Respondent questions the child’s understanding of the concept from the start. In 9.3 shenotes that lack of understanding will interfere with the child’s ability to solve future problems,and she again mentions lack of understanding in 9.4 and 9.5. Finally, in 9.6, she notes theimportance of teaching for understanding. Clearly, throughout the responses, the emphasisis on understanding.

E 0 Respondent advocates more practice.

F 3 Respondent provides a strong and personal rationale for the importance of understanding.

G 1 Respondent wanted to provide the children with an explanation and have them practice.

Exercise Score Comment

H 3

Respondent saw limitations from the start. “No” in 9.3 and “it was not a concreteunderstanding, just short term memorization” in 9.4 indicate the belief that understandingconcepts will help children remember them. Her 9.6 response indicates a conceptualapproach to the topic.

I 2Respondent advocates teaching beyond the explanation of the algorithm but also believesthat the child will be able to answer future problems as a result of the instruction shown inthe first video.

J 0 More practice is what children need.

K 1

Respondent recommends practice and explanation. Although the comment that “if the childdoes not understand that, it would be hard for them to remember how to solve the problem”(in 9.6) is a favorable response, we concluded that the respondent was advocating nothingmore than an explanation of the algorithm.

L 3Respondent doubts that the child will be able to solve future problems and advocates aconceptual approach to teaching the content.

M 0The emphasis in this response is on memorizing an algorithm rather than onunderstanding the concepts.

N 3The emphasis throughout is on understanding, and the respondent differentiates betweenprocedural and conceptual understanding.

Z 3Respondent doubts that the child will remember. The suggestion for the use of visualsindicates a conceptual approach that will help children remember mathematical ideas.

Exercise Score Comment

Y 1Emphasis is on practice and explaining the algorithm (as opposed to understanding theconcepts).

X 0 The child needs more practice.

W 1

The 9.6 comment, “find another method of solving division. Maybe with pictures,” is arecommendation for an explanation that goes beyond explaining the algorithm. But therespondent also indicates that the instruction shown in the video was sufficient for thestudent to remember (only a few will not remember because of bad memories).

V 1 The emphasis is on practice and on explaining the algorithm.

U 2

The suggestion to explain with pictures why the algorithm works and the assumption thatonly students with good memories will remember the algorithm indicate a propensity towarda perspective that understanding mathematical concepts is more powerful thanmemorization.

Rubric for Belief 4––Segment 3.3

Belief 4

If students learn mathematical concepts before they learn procedures, they are more likely to understand the procedures whenthey learn them. If they learn the procedures first, they are less likely ever to learn the concepts.

Description of Rubric

This item was designed to assess respondents’ beliefs about whether children should learn concepts first so that thechildren are better able to understand standard algorithms when they learn them. Respondents are placed in the role ofclassroom teachers and are asked to select an order in which they would focus on particular strategies during a unit onmultidigit addition. Respondents who choose to first teach the standard addition algorithm receive the lowest score,because they provide disconfirming evidence of this belief. Respondents who receive the highest score choose to teachthe standard addition algorithm fourth or fifth and describe the conceptual progression they would want their students toexperience prior to learning this procedure. These respondents explicitly mention that children should understandunderlying concepts (such as place value) before they learn standard algorithms.

Carlos149 + 286

Written on paper

Henry149 + 286

Henry says, "I know that 40 and 80 is 120, and one hundred and two hundred makes 300, and 120 and 300 is 420, and 9 and 6 is 14, so 420 and 10 is 430, and 4 more is 434."

Elliott149 + 286

Written on paper

Sarah149 + 286

Sarah says, "Well, 149 is only 1 away from 150, so 150 and 200 is 350, and 80 more is 430, and 6 more is 436. Then I have to subtract the 1, so it is 435."

MariaManipulatives

= 100Called a flat

= 10Called a long

= 1Called a single

Maria uses manipulatives (base-ten blocks) to solve the problem. Maria says, "I took one flat for the 100 in 149 and 2 flats for the 200 in 286.

I took 12 longs: 4 for the 40 in 149 and 8 for the 80 in 286.

I took 15 singles for the 9 in 149 and the 6 in 286.

Then I counted like this, '100, 200, 300'; then for the longs, '310, 320,

Rubric Scores

0. Responses scored 0 indicate that children should learn standard algorithms before concepts. Respondents may selectthis order for many reasons, but often they state that learning the standard algorithm first will make learning the concept ata later date easier than if the students had learned the concepts first and then were taught the standard algorithms. Weinterpret the choice to share Carlos's strategy first (3.3) as exemplifying that belief.

1. Responses scored 1 still tend to indicate that children should learn standard algorithms before concepts, but therespondents may have an even greater focus on a progression that goes from what they consider the easiest strategy tothe most difficult. We consider this belief to be exemplified in Item 3.3 if respondents choose Carlos’s strategy second; theirexplanations often indicate their desire to order the strategies from easiest to most difficult (in particular they do NOTmention a desire to teach concepts and then standard algorithms).

2. Responses scored 2 indicate some value in teaching the standard algorithm after the students have been exposed to moreconceptual strategies. This aspect of the belief is evidenced, in our view, by the fact that the respondents choose to haveCarlos share 3rd, 4th, or 5th. However, their explanations do not indicate a desire to teach concepts before standardalgorithms. Some other respondents who score 2 do indicate a desire to teach concepts and then standard algorithms, butthey want Carlos to share 2nd. Having Carlos share 2nd (even with a reasonable concepts-to-procedures response)indicates a weak interest in having students learn mathematical concepts first, because learning just one of the moreconceptual strategies first may not provide a strong foundation for students to learn concepts before standard algorithms.

3. Responses scored 3 explicitly indicate an interest in having children learn concepts before standard algorithms. Therespondents may choose Carlos to share 4th or 5th, but they do not mention particular aspects of the conceptual progressionthey selected. Respondents may choose Carlos to share 3rd and indicate a desire to teach concepts before standardalgorithms, but having Carlos share 3rd (not 4th or 5th) indicates a moderate but not strong desire for students to learnconcepts well before they learn standard algorithms.

4. Responses scored 4 indicate that students should have a strong conceptual foundation before they learn standardalgorithms. We consider this belief to be indicated in item 3.3 by respondents who both want Carlos to share 4th or 5th andprovide details about the conceptual progression they would like their students to experience before they learn standardalgorithms. Quite often, a response of 4 includes an explicit statement that the students should understand, for example,place value before learning a standard algorithm.

Sarah's method is morecomplex than Henry's, because it uses subtractionand number sense. Begnining with Henry's methodwould help encourage Sarah's to come about.

Rubric for Belief 4—Segment 9

Belief 4

If students learn mathematical concepts before they learn procedures, they are more likely to understand theprocedures when they learn them. If they learn the procedures first, they are less likely ever to learn the concepts.

Description of Rubric

This rubric focuses on the support that the respondent recommends the teacher provide to ensure that morechildren successfully solve fraction-division problems. In analyzing these responses, look for (a) the kind ofsupport the teacher might supply and (b) the timing of this support. Respondents who suggest that the teachersupply an explanation provide weak evidence of this belief. Although they show interest in conceptualunderstanding, they are insensitive to the timing of conceptual development. Respondents who suggest that theteacher develop the concepts by using visual aids, manipulatives, or story problems provide evidence of this beliefbecause they realize that more than an explanation will be required for children to understand this difficult concept.Those respondents who note that the teacher needs to supply the conceptual support before teaching theprocedure are considered to provide strong evidence of the belief. They realize the importance of providingconceptual support, and they note the importance of the timing of this support.

In coding this response, the coder should focus on responses to Item 9.6. Responses to other parts of the itemgive more information about the respondent’s thoughts on the importance and timing of conceptual learning.Coding this rubric is relatively fast, and interrater reliability is expected to be relatively high because little inferenceis required.

Rubric Scores

0. Responses scored 0 include the view that the child needs only to practice more. Respondents may mention conceptualunderstanding, but do not describe it as something that is needed.

1. Responses scored 1 indicate that an explanation of why the algorithm works should be given to the child but do not include asequence for the instruction. Respondents state that the algorithm and concept should be taught concurrently. They offer noideas for how the concepts should be developed, beyond providing an explanation.

2. Responses scored 2 indicate that to understand the concept, children should have access to something, such as visual aids,in addition to an explanation of why the algorithm works. Respondents have an idea about how conceptual developmentmight take place, but they do not mention that it should come before the algorithm is taught.

3. Responses scored 3 indicate that before learning the algorithm, the child needs to have the conceptual foundation.Respondents suggest ideas for how this conceptual foundation should be laid (such as by using visual aids). They clearlystate that the conceptual work should come BEFORE the work with the algorithm.

Scoring Summary

Score Rubric details

0 • Practice more; no mention of teacher intervention of any kind OR• Practice more of the same kind with some support from the teacher.

1 • The teacher should explain why the algorithm works along with providing more practice.

2 • The teacher should provide a context, visual aids, or both.

3• The teacher should provide an explanation of the concept or experiences with the concept before

working with the algorithm so children can develop conceptual understanding. OR• Children can reason through this kind of problem and never need to learn the algorithm.

Rubric for Belief 5—Segment 2

Belief 5

Children can solve problems in novel ways before being taught how to solve such problems. Children inprimary grades generally understand more mathematics and have more flexible solution strategies than adultsexpect.

Description of Rubric

Each of the two parts of this segment is coded separately; the two part scores are then considered to determineone overall score (see the Scoring Summary).

Responses for this segment were often found to be ambiguous and difficult to code. Scores depend uponwhether respondents are sensitive to children’s thinking and view children’s approaches as legitimate. Somerespondents, however, provide little information on this subject.

2. Read the following word problem:

Leticia has 8 Pokemon cards. She gets some more for her birthday. Now she has 13 Pokemon cards. How many Pokemon cards did Leticia get for her birthday?

2.1 Do you think that a typical first grader could solve this problem? NOTE. The problem could be read to the child.

Yes

No

You answered that a typical first grader could solve the following problem:

Leticia has 8 Pokemon cards. She gets some more for her birthday. Now she has 13 Pokemon cards. How many Pokemon cards did Leticia get for her birthday?

2.2 If a friend of yours disagreed with you, what would you say to support your position?

Here is another word problem. Again, read it and then determine whether a typical first grader could solve it.

Miguel has 3 packs of gum. There are 5 sticks of gum in each pack. How many sticks of gum does Miguel have?

2.3 Do you think that a typical first grader could solve this problem? NOTE. The problem could be read to the child.

2.4 If a friend of yours disagreed with you, what would you say to support your position?

B5–S2

Rubric Scores

0. Responses scored 0 indicate that children will not devise legitimate approaches to the Join Change Unknown andmultiplication problems and thus provide no evidence for the belief that children can devise their own solutionsbefore being shown how to solve problems.

1. Most responses scored 1 indicate that children’s approaches to only one of the two problems will be legitimate.Responses scored 1 do not indicate sensitivity to children’s thinking, although some indicate that children cansolve both problems once they have been taught. These responses are interpreted as providing minimal evidencethat children might be able to solve problems for themselves, but they indicate primarily that children must beshown how to solve the problems.

2. Responses scored 2 indicate that children can generate solution strategies for one of the problems and must betaught the other. They indicate that children can solve some problems independently.

3. Responses scored 3 indicate confidence that children can solve both problems when they have access tomanipulatives. They indicate the respondent’s faith in children’s abilities to devise their own solutions.

They know howmany they have, and many ofthem know how many toys theydon't have in a set of possibletoys to be bought from anymanufacturer. Therefore theywill know at a very early agehow many they received, andoften who a gift came from.

Description of Rubric

Because this segment, unlike most others, does not pertain to a specific domain in mathematics, the responses tendto be more varied than for most other items. We identified eight response types that are represented in the rubric. Otherresponses fit none of our categories.

The focus of this rubric is faith in children’s thinking. Coders are expected to attend to whether respondents expressconfidence that children will be able to devise legitimate solution strategies when confronted with problems of typesnew to them. Responses that indicate doubt receive lower scores.

5. What were your reactions when you were asked to solve a new kind of problem without the teacher's showing you how to solve it?

Rubric Scores

0. Responses scored 0 include an indication that children must be taught how to solve problems before they can solve themon their own. They indicate that asking children to solve problems without first showing them how to solve them isdamaging to children and that solutions of children who have not been shown how to solve a problem will be incorrect.

1. Responses scored 1 include doubts about whether children will be able to solve problems without first being shown howto solve them. The respondents express willingness to present children with problems but also express doubts, makingsuch comments as “to see if they can solve it.” The doubt in these responses takes several forms: (a) The children maybe unable to devise solutions; (b) providing problems will stimulate children’s thinking, but the children are not expected todevise solutions; (c) only a very few children will devise solutions; (d) children will devise various solution strategies, butthey will engage in this practice very rarely. Generally, the solutions will not be evaluated, or children will not be asked toshare their answers.

2. Responses scored 2 indicate that children can devise solution strategies when presented new problems. The responseslack expressions of doubt and are affirmative in nature. They often include a rationale for asking children to solve problemswithout showing them how to do so.

3. Responses scored 3 include positive statements that children can generate their own solution strategies to novelproblems. Respondents suggest that they plan to depend on using novel problems as a focus of instruction and expressfaith in children’s abilities to devise solutions for themselves.

Rubric for Belief 5—Segment 7

Belief 5

Children can solve problems in novel ways before being taught how to solve such problems. Children in primarygrades generally understand more mathematics and have more flexible solution strategies than adults expect.

Description of Rubric

The question to keep in mind in scoring this rubric is “Does the respondent give evidence of thinking that children arecapable of devising solutions for problems like this on their own?” Evidence for this view is first sought in Responses7.4 and 7.5, which may be sufficient to determine a score, but Responses 7.1 and 7.3 may be needed in addition.Responses interpreted as indicating a strong belief that children can devise solutions will immediately (in 7.1) includea statement that the teacher should have offered less assistance. Responses interpreted as weaker evidence of thebelief will include in 7.3 (but not in 7.1) that the child could have done more on his own.

A difficulty of coding this rubric is that the respondent may question whether the child understands his actions on theproblem. Although this is an insightful observation, it is not necessarily an indicator that the respondent thinks that thechild could devise a solution to this problem on his own.

In this part of this survey, you will watch an interview with a child.

The following problem is posed to the child:

There are 20 kids going on a field trip. Four children fit in each car. How many cars do we need to take all 20 kids on the field trip?

B5–S7

Rubric Scores

0. Responses scored 0 do not indicate that the child could solve this problem with less help. Various reasons may beoffered for the child’s need for help. Some respondents state that a child will have to be taught how to solve this kind ofproblem and cannot devise a solution without specific guidance from the teacher. They show no evidence of believing thatchildren can devise solution strategies on their own.

1. Responses scored 1 show minimal evidence that the child could do more thinking for himself. The response mayinclude a suggestion that the child could solve the problem with less help, but this suggestion is not backed up withspecific information on how he might do so. Although the respondent may mention that the teacher could have “backedoff” a bit, this message is not consistent throughout the response.

2. Responses scored 2 include appropriate suggestions for enabling the child to do more of the work in solving thisproblem on his own; suggestions include to provide him with blocks and discuss the problem so he understands it. Theview that children can generate solutions on their own is expressed not in initial reactions to the video clip (7.1, as neededto score 3) but only in response to a question about teaching weaknesses or about whether the child could solve theproblem with less help.

3. Responses scored 3 provide evidence throughout all five parts to this segment that the child may have been capable ofgenerating some of the solution himself. In their initial reactions to the clip, respondents mention that the teacher tookover too much, and in their comments about the child’s ability to solve the problem, they make suggestions for how theteacher could have supported the child in thinking independently on this problem.

Comments on Scoring

0 – 1 DistinctionIf the respondent answers 7.4 No, she scores 0, unless in 7.1–7.3 she gives some indication that the child may havebeen able to do more on his own.

1 – 2 DistinctionThe respondent must respond Probably/Yes to 7.4 to score 2. She might, however, score 1 with this response if sheanswers YES but gives no further evidence that she thinks the child might be able to solve the problem on his own—the “Well, if you asked, then you must think so, so I’ll say Yes” response. To score 2, the respondent must provideideas on how the child will be able to solve the problem with less help.

2 – 3 DistinctionThe distinction between scores of 2 and 3 is related to evidence of the strength of the belief. To be considered toindicate that the belief is strong (scored 3), the response will include immediately (7.1) that the child may have beenable to do more thinking independently and give some indication in 7.1 that the child did not have an opportunity to thinkfor himself. A respondent’s raising this issue only later, in 7.3 or 7.5, is interpreted as indicating a less strong belief;such a response is scored 2.

The teacher gave positivefeedback to the studentabout being a goodcounter and was also veryhelpfull in letting the childsee what the groupsrepresented.

What I like alsocontradicts what I din'tlike. The child probablycouldn't have figured outwhat he was solving hadhe needed to do it onhis own.

The strengths were: Nottelling the child exactlywhat to do rather guide himalong and also the positiveencouragement along theway helped him with hisconfidence in doing theproblem.

I don't think thatthere were any.

Probably I think that he couldhave done it with lesshelp, but it would havetaken him a long time.

Questioning, use ofmanipulatives,beginning the processon a level that the childcould understand anddo (counting), clearquestioning, etc.

He did everything thelady asked him to do, butI'm not sure heunderstands what he did.Counting out the cubesand breaking them intogroups of four, was alldone by her command.Otherwise, I feel it was agood strategy to showthe boy how to solve theproblem. Using cubesand dividing them intogroups is very effective.

Lots of positive reinforcementand energy from the teacher.She asked him to do all thecounting freely. Explained atthe end that what he haddone was division. Sheasked him to try to solve theproblem himself before shehelped him.

She never asked himfor feedback to see ifhe understood whatwas happening withthe groups of cubes.

The teacher couldhave had the studentput the blocks in"cars" instead ofgroups, then cars.She could haveeliminated someconfusion by skippingthe group idea andgoing straight to thecar idea.

Having the student answerbefore using the visualaids let's the teacher gagehow far along the studentis. Also having thestudents think about it andthen use the visualsmakes the problem andmath in general so mucheasier than it seems.

Rubric for Belief 6—Segment 2

Belief 6

The ways children think about mathematics are generally different from the ways adults would expect them to thinkabout mathematics. For example, real-world contexts support children’s initial thinking whereas symbols do not.

Description of Rubric

Coders should focus on whether responses indicate sensitivity to children’s thinking, in particular, whether therespondents recognize that young children typically solve the first problem using manipulatives to add on and can solvethe second problem by making three sets of five. Respondents who show insensitivity to children’s thinking in oneaspect of their responses and sensitivity in other aspects are considered to be providing weak evidence that they holdthis belief whereas respondents who show sensitivity to children’s thinking throughout are considered to be providingstrong evidence of holding this belief.

In considering responses to Items 2.2 and 2.4, coders should keep in mind that the wording of these items includes“convincing a friend” about one’s response. Reliability issues arose when coders were learning to distinguishbetween 0 and 1 scores. Later reliability issues arose in their distinguishing between scores of 1 and 2 for ambiguousresponses.

Note. Coders developed a way of talking about the responses. They noted when they saw a glimmer of sensitivity tochildren’s thinking (for example, noting that the first problem was NOT a simple subtraction problem was a glimmer)and when they saw a negative, which was insensitivity to children’s thinking (“children will write an equation” wasconsidered a negative).

Note that this rubric does not assess the respondent’s holding of Belief 5 (concerning children’s abilities to devisesolution strategies on their own) or of Belief 7 (concerning the amount of guidance provided by the teacher). The focusof this rubric is on whether the respondent recognizes that children’s interpretations of mathematics differ from adults’interpretations. Some respondents discuss teaching approaches that are consistent with children’s thinking. Theirscores are high on this rubric but low score on the rubric for this segment in assessing Belief 5. Other respondentsexplicitly describe how children would interpret the problem but doubt they will be able to solve it. Such responses alsoreceive a high score on this rubric but a low score on the rubric for assessing Belief 5.

Rubric Scores

0. Responses scored 0 indicate that children will approach both problems in the ways that adults do: Children will interpretthe first problem as subtraction and the second problem as multiplication. Respondents may state that children will needto convert the problems into equations before they can solve them. They do not recognize that children might act out thestory problems in accordance with the actions in the problems. They show no sensitivity to children’s thinking in the waysthey respond to this question.

1. Responses scored 1 indicate sensitivity to children’s thinking in one minor respect but insensitivity otherwise.Respondents may, for example, recognize that the Pokemon problem is not a simple subtraction problem but fail torecognize that children could model this situation according to the action in the problem. Others mention that the contextor a visual representation will help children to solve the problem but make other comments that indicate insensitivity tochildren’s thinking.

2. Responses scored 2 indicate sensitivity to children’s thinking for one of the problems but not the other. Respondents maynote that the Pokemon problem is not a simple subtraction problem and that children could solve it by adding on in someway but then go on to note that children cannot solve multiplication because they have not been formally introduced to it.Others receiving this score give a detailed explanation of how children might solve one of the problems but not the other ornote, without providing details, that children can solve both problems by using manipulatives. Respondents give someevidence of understanding the power of children’s approaches, but the evidence is insufficient to convince us that thebelief is fully developed.

3. Responses scored 3 show sensitivity to children’s thinking throughout, either through a detailed explanation of howchildren might solve both problems or a detailed account of how a familiar context and the opportunity to model will enablethe child to solve the problems.

Rubric for Belief 6—Segment 8

Belief 6

The ways children think about mathematics are generally different from the ways adults would expect them to thinkabout mathematics. For example, real-world contexts support children’s initial thinking whereas symbols do not.

Description of Rubric

This item is designed to assess the belief that children think about mathematics in ways different from those adultsmight expect: Respondents are asked whether a word problem concerning fractional parts (without using fractionlanguage or symbols) or a fraction comparison (using only symbols) is easier. Respondents select which of twoproblems would be easier for children to solve, the fraction comparison problem “Which is larger, 1/5 or 1/8?” or acomparison problem set in a real-world context: “Who gets more of a candy bar, those sharing the bar among 5 orthose sharing the bar among 8?” They are also asked to explain their responses. The extensive mathematics-education-research knowledge base indicates that, particularly initially, real-world contexts support children’sthinking whereas symbols do not. (Note that the real-world contexts should be relevant to the lives of the childrensolving the problems.) However, many adults remember having had unsuccessful or unpleasant experiencessolving unrealistic or uninteresting word problems and so tend to believe that solving symbolic problems is easierfor children than solving problems situated in real-world contexts. Respondents who receive the lowest score onthis item state that the symbols are easier for children to understand and indicate a lack of appreciation for the real-world context. In contrast, respondents who receive the highest score not only state appreciation for the real-worldcontext but also recognize that the symbols can be confusing for children. In the latter case, respondents oftenwrite that children might think that one eighth is bigger than one fifth because 8 is bigger than 5 (a misconceptioncommonly held by children).

Note that although in Item 8.1, respondents are asked to rank four fraction problems, for purposes of assessingrespondents’ holding of Belief 6, scorers read explanations of the rankings of only the two problems describedabove (8.1c and 8.1d).

8.1 Place the following four problems in rank order of difficulty for children to understand, and explainyour ordering (you may rank two or more items as being of equal difficulty). NOTE. Easiest = 1.

a) Understand

Please explain your rank:

b) Understand

Please explain your rank:

c) Which fraction is larger, , or

are they same size?

Please explain your rank:

You attend a different birthday party at which eight guests equally share a chocolate bar exactly the same size as the chocolate bar shared at the party Jake attended. Did Jake get more candy bar, did you get more candy bar, or did you and Jake each get the same amount of candy bar?

Please explain your rank:

Consider the last two choices:

___ c) Which fraction is larger, , or are they same size?

___ d) Your friend Jake attends a birthday party at which five guests equally share a very large chocolate bar for dessert. You attend a different birthday party at which eight guests equally share a chocolate bar exactly the same size as the chocolate bar sharedat the party Jake attended.

Item d is easier than Item c.

Items c and d are equally difficult.

Please explain your answer.

Rubric Scores

0. Responses scored 0 tend to indicate that children more easily make sense of symbols than of real-world mathematicalsituations. This view is reflected in the response that solving word problems is challenging for children.

1. Responses scored 1 indicate that real-world contexts can support children's mathematical thinking, but withoutmention of the potential confusion that children may have when trying to make sense of symbols, in particular, fractionnotation.

2. Responses scored 2 indicate both that real-world contexts can support children's mathematical thinking AND thatmaking sense of symbols, particularly fraction notation, is potentially confusing for children.

B. Item d is easier (or Items c and d are equally difficult) AND some appreciation for real-worldcontext is shown or indication given that Item d is easier to visualize

2Item d is easier (or Items c and d are equally difficult) AND Item d is easier because of the real-world context or is easier to visualize ANDItem c is more difficult because numerals are more abstract or confusing (or Item c is moredifficult to visualize).

Comments on Scoring

• When coding, read the response to Item 8.2 first, then read the responses to Items 8.1c and 8.1d.• When the responses to Item 8.1c or 8.1d appear to conflict with the response to Item 8.2, give MORE weight to the

response to Item 8.2.• Although the respondents’ rankings of all items are included with their explanations, the rankings are not used

explicitly in determining a belief score on this item. Use the rankings cautiously if you seek additional informationabout the respondents’ explanations, because some respondents misinterpret the directions and rank the mostdifficult problem as 1. This error is sometimes, but not always, evident from the explanations.

C is easier I said that c is easier than d butnow that I re-read the problems Iam not really sure that is what Ithink now. Normally I think thatword problems are more difficultfor children but in this situation Ithink that maybe the wordproblem would be easier tounderstand because it is in astory that may be easier tounderstand.

H 1Item c is easier; appreciation shown for real-world context and for the potential confusion of thesymbols. This respondent also worries about the length of the problem, but because of supportfor real-world context to help children understand, response is scored 1.

I 1Item d is easier; the "concreteness" of the word problem to support children's understanding isnoted. Although the sentence "it's not just numerals on the page" mentions symbols, it does notindicate that the symbols might be confusing for children.

J 0Item c is easier; appreciation not shown for the real-world context to support children'sunderstanding

K 0Item d is easier but appreciation for real-world context unclear. Response 8.2 is vague, andResponse 8.1d states that word problems are too challenging for children.

Z 2Item d is easier; (weak) appreciation shown for real-world context (in 8.1d and 8.2) AND for thedifficulty students may have interpreting the fractions (in 8.1c). (Weak 2 because theappreciation for real-world context is qualified.)

Y 1

Item d is easier; the statement that real-world context provides a visual is interpreted to meanthat the context helps the child to solve the problem. (This response is not scored 2 becausealthough the respondent writes that c is similar to d except that c has no visual, we did notinterpret this contrast to show that the respondent thought that the lack of a visual couldpotentially make the problem confusing for children to understand. The sentence, instead,seemed to convey how items c and d are different.)

X 1Item d is easier; appreciation shown for the real-world context but not for the difficulties inherentin the symbols themselves (but instead for aspects of the procedure of finding a commondenominator).

W 1Item c is easier; in general, appreciation is shown for the real-world context, although therespondent states that this particular context is too long. This response is not scored 2,because Item c is selected as easier than Item d.

Item d is easier, but Response 8.2 concerns the difficulty of fraction comparison, not the waycontext supports a child’s thinking. (Although context is weakly supported in 8.1d, refer toscoring note that if responses to 8.1c or 8.1d conflict with the response in 8.2, more weightshould be given to the response in 8.2.)

U 0Items c and d are equally difficult; appreciation not shown for real world context’s support ofchild's understanding. The respondent mentions the difficulty thinking of fifths or eighths, butbecause of the lack of support for the real-world context, the response is scored 0.

Rubric for Belief 6—Segment 9

Belief 6

The ways children think about mathematics are generally different from the ways adults would expect them tothink about mathematics. For example, real-world contexts support children’s initial thinking whereas symbolsdo not.

Description of Rubric

In scoring responses for this segment, consider whether respondents suggest the use of representations otherthan symbols to teach division of fractions. Responses indicating that work with manipulatives or visuals shouldprecede work with symbols are interpreted as providing strong evidence of this belief. Respondents whosuggest that the teacher provide an explanation, more practice, or both are considered to provide no evidence ofthis belief. We interpret suggestions that symbols and other representations be taught simultaneously as someevidence of this belief.

Focus attention on the responses to Item 9.6 and then consider whether in 9.1 the respondent discusses theimportance of using representations in teaching fractions. Other responses should be skimmed for any relevantinformation. Reliability on this rubric was quite high because the rubric is relatively objective.

9.5 How typical is this child? If 100 children had this experience, how many of them would be able to solve a similar problem 3 days later? Explain.

of 100 children could solve a similar problem later.

9.6 Provide suggestions about what the teacher might do so that more children would be able to solve a similar problem in the future.

Rubric Scores

0. Responses scored 0 indicate that for students to master this procedure requires only work with symbols.Although some respondents may express concern about conceptual understanding, they do not mention that otherrepresentations will help children better understand the concept. They are not considered to show evidence ofholding this belief if they do not suggest that the teacher present the concept using some other means.

1. Responses scored 1 indicate that the teacher should provide the children with other representations in addition tothe symbols.

2. Responses scored 2 indicate that children’s reasoning for division of fractions will be better supported with otherrepresentations instead of or prior to manipulation of symbols.

Scoring Summary

Score Rubric details

0• Practice more (with no mention of teacher intervention of any kind)• Practice more of the same kind with some support from the teacher.• The teacher should explain why the procedure works along with providing more practice.

1 • The teacher should provide a context or visual aids in conjunction with the algorithm.Difficulties children will have with symbols not acknowledged.

2• Children can reason through such problems, and the teacher should support this reasoning

with the use of visual aids; the algorithm should be introduced after the use of visual aids, ifat all, or children will have difficulties with the symbols.

The childunderstood howto use thealgorithm tosolve theproblem, but shealmost seemedlike a robot. Sheused the exactsame words andsteps as herteacher. Shedidn't need tothink at all, and Idon't think sheunderstood whatshe was doing.

Not much. Ithink she wasjust repeatingwhat herteacher hadshown her,without anyunderstandingof division offractions or whyshe was doingwhat she wasdoing.

No. She mayremember somesteps of theformula, butuntil she clearlyunderstandswhy she isdoing what sheis doing, shewon't be able tosolve similarproblems,especially ifthey are just alittle bitdifferent thanthe ones thatshe had beentaught to solvewith thealgorithm. Thatalways throws achild off track,when theproblem theyneed to solve isdifferent thanthe ones theylearned how tosolve with thealgorithm,unless theyclearlyunderstandmathematicallywhy they aredoing what theyare doing.

That was what Ithought was goingto happen. Thechild had been ableto repeat what theteacher had donethe day before,without anyunderstanding, likea robot. But whenshe had to comeback the next day,she didn't knowwhat to do, or whyto do it. It had justbeen numbers and aformula to her, notunderstanding.

I think that somechildren wouldremember what todo, just becausethey may have agood memory.Others may justtake a goodguess and beable to solve it.

I think the teacherwould need to usesome visual aids anddrawings to get thechildren to betterunderstand it. Evenwhen I was a child,before I took my Math210 class, I used tomake drawings to try tofigure out how to solvemath problems. Thatwas what worked bestfor me, and wouldprobably work best forat least some otherchildren. She coulduse real life examples,but not word problemswritten down on paperyet, and have themsolve those real lifeproblems. Then theteacher needs to relatethe real life problems tothe ones on the paper.If she can clearly getacross the message asto why the children aredoing what they'redoing, I think that theywould understand andbe able to solve similarproblems in the future.

The teacher waspleasant andhelpful, but thiswas simply rotemanipulation ofabstract symbolsthat had little ifany meaning tothe child.

Based on whatwe say here,none at all(although shemight knowmore -- shenever had thechance todemonstrateanyunderstanding).

Yes. The lengthof time here issignificant andwhat else thechild does in themean time issignificant. If thiswere 3 monthsafter this sessionand the child haddone no otherfraction lessons,the odds of recallare minimal. Thisis a pretty easyprocedure

It is clear the childforgot thealgorithm and hadno idea what to do.

As I noted before,there are a lot ofmitigating factors.

I would take a singleobject (fraction bar,candy bar, fractioncircle) and work on theidea of how many 1/3'sthere are the singleobject. I would then goto 6 of those objectsand how many 1/3'sthere are in the 6objects.

Rubric for Belief 7—Segment 5

Belief 7

During interactions related to the learning of mathematics, the teacher should allow the children to do as much of the thinking as possible.

Description of Rubric

This is the only segment on the survey that is not situated within a particular mathematical context and is instead moregeneral. This fact may contribute to this rubric’s being one of the more difficult rubrics to code. It requires closescrutiny because the responses to this segment vary greatly We identified eight kinds of responses to this segment.

The segment was designed to measure (a) the respondents’ beliefs about the role of the teacher and (b) thedegree to which respondents state they are willing to share the authority in the class with their students. Item5.0, about the respondents’ personal experiences with problem solving, serves to stimulate their thinking.Responses to Item 5.0 occasionally provide evidence about the belief, but coders should focus on answers toItems 5.1 and 5.2 because they tend to be more informative. In coding this segment, attend to how therespondents plan to use children’s thinking in their teaching. In coding, we asked ourselves, “Does therespondent indicate that the students’ approaches will be as legitimate as the teachers’ approaches?” We takeas strong evidence for this belief indications that children’s thinking will be central to the respondent’sinstruction. We infer a respondent’s plan to provide children with problem-solving opportunities but not use thechildren’s thinking in instruction as weak evidence of this belief. Such a respondent plans to allow students todo mathematical reasoning but will not use it as an integral part of instruction. A respondent who intends to usechildren’s thinking in instruction, but only infrequently, is considered to provide evidence of holding the belief.

5. What were your reactions when you were asked to solve a new kind of problem without the teacher's showing you how to solve it?

5.1 When you are a teacher, will you ever ask your students to solve a new kind of problem without first showing them how to solve it?

Yes

0. Responses scored 0 indicate that students will never be asked to solve problems without first being shown how todo so. The respondents state that children need to be provided with approaches and cannot devise them on theirown. They do not show evidence of believing that children should think for themselves.

1. Responses scored 1 indicate that children will be asked to solve problems without being shown how to solvethem, but do not indicate that this work will be an integral part of instruction. The respondents will provide childrenwith problem-solving opportunities, but only in limited circumstances: for assessment, to stimulate thinking beforeformal instruction, or after some introduction by the teacher. In some cases they state good reasons for allowingchildren to solve problems for themselves but also state that the teacher should show some strategies as well.

2. Responses scored 2 indicate that children will be asked to solve problems without being shown how to solve themand that the children’s approaches will be used as an integral part of instruction. The respondents, although theynote the importance of this practice, may use it infrequently. Some responses indicate that children’s approacheswill be as legitimate as the teacher’s and will be useful to other children.

3. Responses scored 3 indicate total commitment to students’ solving problems without first being shown how to doso. Problem solving will be an integral part of the respondents’ instruction. The response includes a soundrationale for the importance of children’s devising strategies and solving problems themselves and doing so often,if not always.

Rubric for Belief 7—Segment 7

Belief 7

During interactions related to the learning of mathematics, the teacher should allow the children to do as much of the thinking as possible.

Description of Rubric

The focus in this rubric is on whether the respondent finds the teacher’s guidance to be excessive.She did not provide the child with an opportunity to devise a solution on his own. Instead she told him what to dofor each step. Respondents who are considered to strongly hold the belief that teachers should allow children todo as much of the thinking as possible note in their initial reaction to the clip that the teacher should have giventhe child an opportunity to solve the problem for himself. Others express this view only after being asked todiscuss the weaknesses in the teaching. Some respondents note that the teacher’s guidance is good and thennote that it was excessive. These contradictory responses are interpreted as weak evidence of the belief. Somerespondents find no weaknesses in the teaching at all, and some think that the teacher should do even more tohelp the child.

The difficulty in coding this rubric is in deciding between scores of 1 and 2. Determining whether the respondentis contradicting herself in her responses is sometimes difficult.

In this part of this survey, you will watch an interview with a child.

The following problem is posed to the child:

There are 20 kids going on a field trip. Four children fit in each car. How many cars do we need to take all 20 kids on the field trip?

Rubric Scores

0. Responses scored 0 include overall satisfaction with the guidance provided by the teacher or suggestions for how theteacher could have helped the child more. These responses are interpreted as showing no evidence for this belief,because the respondent presents no critique of the teacher’s taking over the thinking of the child.

1. Two types of responses are scored 1. One type includes a seeming contradiction. The respondent expressessatisfaction with the guidance provided by the teacher but later suggests that the teacher could have provided less help;thus the respondent indicates some interest in children’s thinking for themselves without being troubled when the teacherdoes not allow for such thinking. The second response type includes a conclusion that the problem presented was toodifficult for the child. The respondent does not address the extent to which the child should be allowed to think for himself,because she thinks that for this problem the child is unable to think for himself.

2. Responses scored 2 do not show satisfaction with the guidance provided by the teacher although the response mightinclude positive comments about the use of manipulatives or the real-world context of the problem. Although therespondent does not comment positively about the help provided by the teacher, she critiques the teacher for leading thechild excessively only when asked to point out the weaknesses in the teaching. She does not raise this concern beforebeing asked about the teaching weaknesses. We interpret this response as weaker evidence for the belief than a critiqueof the teacher’s excessive help in Response 7.1.

3. Responses scored 3 reveal, immediately in Response 7.1, a strong negative reaction to the guidance provided by theteacher. The belief that teachers should allow children to think for themselves is interpreted as being so strong that therespondent notes positive aspects of the episode only when asked to do so in Item 7.2.

I think that the child's first answerstood out to me. depending on thechild's grade, i would have thought thathe would have tried to solve theproblem out and get to the correctanswer. but, since he was young, theway he used the blocks was a goodway to solve the problem.

I think that the blocks is agood way of teaching in thisepisode. it gives the child avisual or something to use forcounting rather than trying tosolve it with a pencil andpaper.

Instead of saying "groups" in thebeginning, i would ask the child topretend that you want to put 4 people ineach "car." Because it seems like thechild didnt know why he was taking 4blocks away each time, so that was aweakness. I would maybe ask the childto draw out at least 7 cars on the paperand then put 4 in each car until thereare no more blocks (poeple) left. thentell him to count how many cars heused out of the seven. i think that ifyou give a child a visual or some sortof picture, it would be easier to solveand understand the problem.

He couldn't solve the problem with outsome scaffolding and somemanipulatives but he did it when he gotwhat he needed.

Use of manipulatives, talkingthrough it with the student,led him where he needed togo.

1 Response seems to becontradictory. The childcould not have solved theproblem without the helpthat the teacher provided(7.1), but the child wasgiven too much help (7.3).

The child just guessed when he wasfirst asked the problem. He didnt'attempt to write it down or solve for theanswer. Then when he used blocks hewas able to understand that 5 carswould be needed for 20 kids.

The strengths were the visualaid, the blocks. The blocksreally help children see theproblem rather then just onpaper.

The teacher should have firtst given theblocks to the child and then told himtheses are 20 kids if four can fit onlyone car how many cars are needed.Then let him figure it out on his own.After he did his understanding thenshow him how to do it if he got it wrong.

As I said before manipulatives arevery powerful. They make theabstract concrete.

The teacher used manipulatives andexplained every step of the procedureas she thought out load about theproblem.

No obvious weaknesses.

before the child used manipulatives, hereally couldn't even fathom what it was heneeded to do. as soon as themanipulatives were introduced, he seemedto get more of a focus, and with theteacher's help, he got the problem right.

manipulatives made theconcept concrete. the childcould actually see the 4"kids" in each of the 5"cars."

it seemed the teacher led the child to theanswer, and I would want to see if thechild, once introduced to themanipulatives, could have figured outwhat to do with some questioning from theteacher, rather than the teacher saying"now do this, and this etc"

Well first the child guessed when theycouldnt think of it on the top of their head.Then he was asked to use blocks. It sortof seemed like he was really being pushedin the direction the interviewer wanted himto go instead of going their on his own.

The teaching had a lot ofpositive reinforcement, Ihave to give it that. Shewas very positive when hedid something and sheseemed really positivethroughout the entire video.

She pushed the child a little too hardinstead of letting him go there on his own.Maybe it was because he wasn't going tofind it on his own, but I really dont thinkhe knew why he was counting all thegroups of four, other than because hewas told to.

I'm not sure that the child actuallyunderstod what he had done. It seemedas though the interviewer led him throughthe solution and the child was justfollowing the steps. I wonder if he wouldbe able to apply this method to similarproblems.

The teacher's encouragementand ability to stay with thechild seemed a strength.

Again, I'm not sure that the way theinterviewer led the child through thesolution really added to hisunderstanding. He was able to derivethe correct answer, but I don'tnecessarily think that was the mostimportant part of the interview.

The child worked the problem out withblocks and got the right answer. He did agood job.

The blocks helped him to seewhat the problem was allabout.

The teacher spoon fed him theapproach. She could have backed off tosee what he could do with less help. Hedidn’t get a chance to think for himself.

Yes, children need math manipulatives,especially at a young age when they can'tthink abstractly. It was also good on theteacher's part to mention to the child hedid an "adult" math problem. It made thechild feel smart and good about math.

She complimented the child.She was kind, encouraging, andshe used manipulatives to helphim solve the math problem.She was also very pacient.

I didn't see any.

What stood out for me was how mucheasier it was for the chidren to solve theproblem when they had the cars tomanipulate and count for a total.

Allowing the children to manipulateand asking good questions to helpthem think about the problem andlead them along the right path.

Sometimes the teacher seemed tobe leading them too much to theanswer and not allowing them tothink on their own.

The teacher was very encouraging.Even when the child guessed 10cars, she applauded his efforts.Upon seeing the groups of blocksdivided up as "cars" he understoodthe concept. Visualization is veryimportant for later on when he reallybegins to perform divisionproblems.

The instructor first related the word problem tohim, making the child feel like they areplanning a camping trip for his classroom andthey need enough cars to accomodate hisclassmates. She encouraged him and gavehim praise, such as "you're such a goodcounter." She identified when he was guessingbut did not give him a hard time about it,instead she persisted till he understood andmade him feel like he had performed "big kidmath." That's good for his confidence which isimportant in perfoming math, especially infront of someone, so it should help him in hisclassroom.

Perhaps she should havestepped back a little and let himexplain how he intended tomake the 20 blocks into 5 cars,he may have been able to do itwithout her touching the blocksand sorting them around forhim.. After there were 20blocks pulled out I would haveliked to see what he did nextwithout her prompts.

Jq7.1 q_video_7.2_reaction q_video_7.3_reaction Score Commentwhat stood out what how thestudent didnt try to come up with asolution at the beginning he justguessed. that is what moststudents would do at his age. also,i liked the way the teacher helpedhim through the problem but i don'tthink he understands and would beable to do another problem on hisown.

The teacher did a good job complimenting thestudent and helping him through the motions.

the teacher could haveexplained that you have to splitup the kids into each car byfours and then told him to putthe blocks in groups. maybe ifhe did more of it on his owninstead of her telling himdirectly each step, he wouldhave learned it more.

Kq7.1 q_video_7.2_reaction q_video_7.3_reaction Score CommentThe manuplatives worked great inthis problem. When te child wasasked to solve the problem, heguessed. With a little coaxing itwas easy for the child to see thatfour kids fit in each car.

Well, I found myself curious toknow how that kid would havesolved the problem if he had beengiven a chance. The method theteacher walked him through wasone that many kids probably do.But I saw it coming from theteacher and not the kid. It wouldhave been interesting to see whathe would have done if she hadprobed his first answer (10 cars) abit more, perhaps leading to therealization that 10 cars were toomany. What would he have donethen?

It was great that she asked him how hefigured out his first answer of 10 cars. Askinghim to show the 20 kids was also potentiallyhelpful. In addition, it was nice that she didnot reveal by her demeanor whether hisanswer was correct.

She led him through a methodof her choice. This methodseems like a great one, but hemight have been able to figurethis problem out himself. Shecould have asked questionsabout his initial answer,possibly leading him to aperturbation, which might haveresulted in him thinking aboutthe problem differently or findinghis own solution. Her behaviordid not allow him thatopportunity.

Mq7.1 q_video_7.2_reaction q_video_7.3_reaction Score Comment

It was obvious that the student wastaking a complete guess at theanswer and did not understand thedivision question. I was surprisedthat he did not attempt to use theblocks at first or work the problemout with the paper and pencil.

The teacher was friendly, she tried to makethe question fun, and she made solving thequestion fun.

I think the teacher should haveprompted the student to utilizethe materials on the table ifnecessary. I think it ispossible that the student couldhave solved the problemwithout help if he were told touse the blocks.

Nq7.1 q_video_7.2_reaction q_video_7.3_reaction Score Comment

The interviewer prompted the childa lot. On his own I don't think hecould have solved it, but it wasgood that she had him think itthrough. With the prompts he couldfigure it out.

The interviewer did not give him the answer,she just prompted him in the right direction.That was good.

there were a couple of strengthens to thisteachers approach in helping the boysolve the division problem. sheconstantly gave postitive feedback to theboy which was great, not only did shegive postitve reinforcement, but alsohelped the boy in showing himmanipulatives. and how to use them.she also took her time, and did not rushthe boy into solving an answer quickly.

there were a couple ofweaknesses by the teacher notwriting the probelm down onpaper. she told the boy theprobelm out loud. seeing howthe child is a visual learner, itwould have been to his benefit tosee the problem, instead ofvisualtaion. while the use ofmanipulatives was great, shejumped in and showed the boythe manipulatives and how to usethem. she shoudl of waited a bitlonger to see how the boy wasging to solve the problem,instead, of rushingh right to thecubes

I think it was good to suggest that hecount out 20 kids. I think a student mightneed this liitle push to get them started,and he may need a few more triggerquestions i.e. Can you show me 4 kids inone car?

B 0 Complete satisfaction with the guidance offered by the teacher indicated.

C 2Neither satisfaction nor dissatisfaction with the guidance provided by the teacher is expressed in7.1 and 7.2. Comments on strengths limited to satisfaction with use of manipulatives. Critique in7.3 is consistent with other comments about the video.

D 3Concerns expressed in 7.1 (before question on weaknesses was posed) about the guidance ofthe teacher. The teacher guidance was noted right away and elaborated on in 7.3.

E 3That the teacher’s guidance did not build the child’s understanding is noted in the initialresponse. View of the importance of teachers’ giving children opportunities to devise solutionsfor themselves is sufficiently strong to be of concern immediately.

Y 0Respondent values children’s opportunities to devise solutions but states that the child in thevideo was allowed to think on his own to solve the problem. She expresses no concern about theguidance offered by the teacher.

X 1Manipulatives are the focus of the response to 7.1. Approval of the teacher’s guidance expressedin 7.2: The teacher took her time and did not rush the boy. In 7.3 respondent contradicts thisstatement and suggests that the teacher not rush the boy to use the manipulatives.

W 2

Although the respondent states that the child needed a little push to get him started and a fewtrigger question, she criticizes the teaching as being too guided. Thus, she is dissatisfied withthe teacher’s guidance and notes that the child does not understand his work. Mention of herconcern about the guidance offered by the teacher in 7.1 would be interpreted as strongerevidence of this belief. This ambiguous response could be scored 1, but we interpreted thecomments in 7.2 to mean that the respondent favored asking only a few trigger questions andconsidered the number of guiding questions in this interaction excessive.

V 3This limited response indicates, in 7.1 and 7.3, criticism of the guidance offered by the teacher.We scored this response a weak 3.

U 0The suggestion that the teacher might have pursued the child’s guess is insufficient evidence ofthe belief to score the response 1. The respondent states (7.2) that the teacher gave just the rightamount of help. Indication that the teacher helped too much is required to score 1.

T 2

That the teacher may have helped too much is noted in 7.3, but in 7.1 and 7.2, dissatisfaction withthe teacher’s help is not expressed. We interpreted the ambiguous statement “'The teacher wasclear in what she wanted for the problem” to mean that the teacher was prepared withmanipulatives for the child to use.

VISurvey Functions

Survey Functions

The Integrating Mathematics and Pedagogy (IMAP) Web-Based Beliefs Survey includes several functions to provide aresearcher flexibility when measuring beliefs. By using the Accessing Data functions, you can view data collection in realtime and easily download collected data. All administrator functions are protected by a password that can be changedand maintained.

By typing admin.asp after the address or URL of the survey (for example, http://www.imapsdsu.org/admin.asp), you canaccess the Survey Administrator screen.

Before you can continue to the Survey Administrator screen, you will be prompted to enter a password. The defaultpassword is password.

Customizing the Survey

We have created three options for customizing the survey:

1. (By belief) From the Beliefs list, select the beliefs of interest to you; the appropriate segments of the instrument will beautomatically assembled for you.

2. (By segment) From the Segments list, select the segments to include.

3. (By both) Select some beliefs and some segments.

After you have selected from the lists of Beliefs and Segments, click Submit at the bottom of the screen to save yoursettings. A message will be displayed to confirm your settings.

Browsing the Survey

To see a table of all the items that comprise the Beliefs Survey, use Browse the Survey, found on the SurveyAdministrator screen. Click on an item to display that section of the survey. A set of navigation buttons is located at thebottom of each page. Click the arrows to move backward or forward in the survey. Between the arrows is a button youmay use to return to the table of items. Responses cannot be submitted from this version of the survey.

You have three options for cusomizing the survey:

(1) From the Beliefs list, select the beliefs of interest to you; the appropriate segments of the instrument will be automatically assembled for you.(2) From the Segments list, select the segments to include.(3) Select some beliefs and some segments.

BELIEFS

1. Mathematics is a web of interrelated concepts and procedures (school mathematics should be too).

2. One's Knowledge of how to apply mathematical procedures does not necessarily go with understanding the underlying concepts. That is, students or adults may know a procedure they do not understand.

3. Understanding mathematical concepts is more powerful and more generative than remembering mathematical procedures.4. If students learn mathematical concepts before they learn procedures, they are more likely to understand the procedures when they learn them. If they learn the procedures first, they

are less likely ever to learn the concepts.

5. Children can solve problems in novel ways before being taught how to solve such problems. Children in primary grades generally understand more mathematics and have more flexible solution strategies than the teachers, or even their parents, expect.

6. The ways children think about mathematics are generally different from the ways adults would expect them to think about mathematics. For example, real-world contexts support children's initial thinking where symbols do not.

7. During interactions related to the learning of mathematics, the teacher should allow the children to do as much of the thinking as possible.

Beliefs About Learning or Knowing Mathematics, or Both

Beliefs About Children's (Students') Learning and Doing Mathematics

SEGMENTS 2. Missing-addend problem in Pokemon-cards context 7. Video 1 - Teacher working with boy on 20 + 4 measurement-division story problem.

3. Six examples of student strategies to solve 149 + 286. 8. Fraction operations and comparison problems, with and without context.

4. Two children's written work for solving 635 - 482. 9. Video 2 - Teacher shows child fraction-division algorithm. Video 3 - Child attempts to use algorithm 3 days after instruction.

5. When you are a teacher, will you ask your students to solve novel problems? 10-15. Biographical Likert-scale questions.

6. How sure are you that you want to become a teacher? Segments 6 and 10-15 do not assess beliefs. They are included to collect biographical information.

The version of the survey included in this manual is only for browsing; no data can beentered or submitted. The message “Button not supported in Manual” will appear if you try to submit data.

Table of Contents for Browse VersionThe survey items are listed and briefly described in the Table of Contents. Each item is linked to its item number in the Table of Contentsand can be accessed by clicking on the link. Movement within this version of the survey is possible from the Table of Contents to anypage as well as from page to page (using the Acrobat page-forward or page-back arrows). Bookmarks have been nested under the Tableof Contents bookmark so that you can select any of the three pages of the Table of Contents.

Branching is the one feature of the survey not available for examination in this version. For each item that leads to branching in thesurvey, one response was chosen to be shown in this version. For example, in Item 2, respondents are asked whether a first-grade childcould solve a certain problem. Within the actual survey, the next page the person sees is determined by his or her response to thatquestion. Within this version of the survey, we include only one of the branches (in this case, the one taken if the respondent answers inthe affirmative).

Carlos 149 + 286

Written on paper

Henry 149 + 286

Henry says, "I know that 40 and 80 is 120, and one hundred and two hundred makes 300, and 120 and 300 is 420, and 9 and 6 is 14, so 420 and 10 is 430, and 4 more is 434."

Elliott149 + 286

Written on paper

Sarah149 + 286

Sarah says, "Well, 149 is only 1 away from 150, so 150 and 200 is 350, and 80 more is 430, and 6 more is 436. Then I have to subtract the 1, so it is 435."

Does Carlos's reasoning make sense to you?

MariaManipulatives

= 100Called a flat

= 10Called a long

= 1Called a single

Maria uses manipulatives (base-ten blocks) to solve the problem. Maria says, "I took one flat for the 100 in 149 and 2 flats for the 200 in 286.

I took 12 longs: 4 for the 40 in 149 and 8 for the 80 in 286.

I took 15 singles for the 9 in 149 and the 6 in 286.

Then I counted like this, '100, 200, 300'; then for the longs, '310, 320, 330, 340, 350, 360, 370, 380, 390, 400, 410, 420'; then the singles, '421, 422, 423, 424, 425, 426, 427, 428, 429, 430, 431, 432, 433, 434, 435.'

So the answer is 435."

4. Here are two approaches that children used to solve the problem 635 – 482.

Lexi 5613 5 – 4 8 2 1 5 3 Lexi says, "First I subtracted 2 from 5 and got 3. Then I couldn't subtract 8 from 3, so I borrowed. I crossed out the 6, wrote a 5, then put a 1 next to the 3. Now it's 13 minus 8 is 5. And then 5 minus 4 is 1, so my answer is 153."

Ariana

635 – 400 = 235235 – 30 = 205205 – 50 = 155155 – 2 = 153 482

Ariana says, "First I subtracted 400 and got 235. Then I subtracted 30 and got 205, and I subtracted 50 more and got 155. I needed to subtract 2 more and ended up with 153."

4.1 Does Lexi's reasoning make sense to you?

Yes No

4.2 Does Ariana's reasoning make sense to you?

Yes No

4.3. Which child (Lexi or Ariana) shows the greater mathematical understanding?

Lexi Ariana

Question 4 (continued)

Here are those two approaches again so that you can refer to them to finish this section.

Lexi 5613 5 – 4 8 2 1 5 3 Lexi says, "First I subtracted 2 from 5 and got 3. Then I couldn't subtract 8 from 3, so I borrowed. I crossed out the 6, wrote a 5, then put a 1 next to the 3. Now it's 13 minus 8 is 5. And then 5 minus 4 is 1, so my answer is 153."

Ariana

635 – 400 = 235235 – 30 = 205205 – 50 = 155155 – 2 = 153 482

Ariana says, "First I subtracted 400 and got 235. Then I subtracted 30 and got 205, and I subtracted 50 more and got 155. I needed to subtract 2 more and ended up with 153."
